With the discussion re: Mac gear recently, I should mention that I have a
pair of C-22's gathering dust in my basement. If anyone is intersted in
taking them off my hands for a fair price, let me know. I have no use for

Mac the Scope 1.2
<swmark@channld.com>
Channel D announces Mac the Scope 1.2, a feature and performance upgrade
of our digital audio-frequency spectrum analyzer and oscilloscope
software.
Mac the Scope turns a Macintosh with sound input/ output capability into
a full-featured audio-frequency spectrum analyzer, oscilloscope, and
signal source. Mac the Scope includes a two-channel, mini-plug to dual
RCA-plug interface cable.
Mac the Scope is compatible with 68k Macs having sound input capability
and a math coprocessor, in addition to all PowerPC machines. Only 4 MB
free RAM needed; System 7.1.1 and QuickTime 1.6.1 or later are required.
Upgrades are free to users who purchased Mac the Scope on or after
November 1, 1997, and will be shipped automatically to registered users.
Upgrades for other users are priced at $49, plus $10.50 shipping and
handling, and include a revised user guide.
Mac the Scope retails for $299.

Does anyone here have any experience running McIntosh tube amplifiers
in triode mode, or have any opinions on this matter?
I've modified a pair of MC-60's in this fashion and I love the way
they sound, but have gotten negative opinions about the practicality
and performance compromises of this modification.
I'll go into further detail if there's any interest in this thread.

Hi Guys,
I was surfing the Madisound web site last night looking for some
driver info and pricing. Anyway, while checking their specials I found a
page on some GE metalized polyprop caps that they have. Assorted values,
mostly 5%, up to 10uf, 600 volt. The most expensive cap on the list is
$3.50/qty 1. The caps are series GE 40L (10% - only 4 values available),
GE 41L (5%, 18 different values ranging from .68uf to 10uf), and series GE
42L (5%, 17 different values ranging from .022uf to 2uf, none lower than
850vdc!). Anybody know more about these caps?
Madisound is at: www.madisound.com

Joe: Hello. Respectfully....I don't get your point. There is no magic at all
in winding transformers.....we used to wind all of our units by hand (years
ago) and today only a portion of our units are wound manually by hand although
most of the other steps are still done manually. It is a skilled craft and
does have some proprietary elements involved in the methods and techniques
that we use.
For instance many of our units are now bobbin wound just like the vast
majority of our competitor's products (the likes of Tango, Tamura, Nature
Sound and etc). JC Morrison of all folks (thanks Jay) was instrumental in
getting me to realize that on bobbins there are new design opportunities that
if optimized could result in good products. As a side benefit we were able to
also reduce our costs and pass along these savings to the consumer. My
*instinct* (lord knows I can be wrong on that count) is that the layer wound
by hand coils are still the superior jobbies....but we could not compete
dollar for dollar with us investing many hours of hand labor in the winding of
a coil while many (not all) of our competitors were winding on bobbins in a
random fashion and selling them at the same price points or lower cost than
our products.
So we still offer the hand wound units but to a different audience and all of
our top of the line units are still done by hand. This will continue to be
the case unabated.
Regarding Herb's barbs.....I could have turned this around on Herb and said
fine....I will show you mine....if you show me yours. Show me your integrated
mining, refining, smelting, drawing, and enameling capabilities for magnet
wire production (which AN claims is done in-house) but simply did not want to
prolong the controversy and I am mature enough about business to know that
many portions of a company's operations are closely guarded secrets..... I
would personally consider it improper to ask Herb to do that. Likewise his
request at that time (if it was made...I don't recall) would have been turned
down for these very same reasons.
>This whole propritory business is a bitch to maintain..don't know if

And one of the best ways to compromise this integrity is to have an "open
house" policy. I sell products which can be judged and evaluated on their
performance merits....it is not a license to the public or our competitors to
come and learn our techniques and methods free of charge. That is not what I
sell.

As far as I know, the Magnequest IT is a 1:1, 5K primary capable of
handling 20mA of current *but no more* (this is important because of the
bifilar windings). It costs around $100. I think Doc B's Electronic
Tonalities sells them--check his web site at www.bottlehead.com

Nope. The bifilar windings don't influence the current capacity. They limit
the warantee (none) because the bifilar scheme is dicey if there is a high
DC voltage present on the windings. The bifilar scheme means that wires at
two very different potentials may be side by side with only the varnish on
the wire as an insulator. A road to low capacitance and great sound, yes,
but a dicey proposition if there exists a pinhole in the varnish at the
wrong spot. This is one reason we recommend the parafeed version, which
would have no high voltage on it as long as the primary side coupling cap is
installed between the driver plate and the primary, as recommended.
Granted, if you run way too much current through them you might overheat
them and affect the varnish hardness, I suppose, but that's not the reason
for the current limit in the conventional RIT-5. As usual, the current limit
should be heeded because more DC flux will lead to distortion, starting at
the bottom end, where ITs have the most difficulty meeting Anna's standard
of realism ;^)>. And this is another good reason for a parafeed
configuration, the "DC linearizes the core" arguments aside. I haven't had
the pleasure of the parafeed RIT-5 myself yet, but I have a hunch it will
help resolve the one shortcoming I found with ITs in the past, soft bass.

I should have added that the DC flux is only part of the determining factor
of the 20mA current limit on the air gapped version of the RIT-5.
The other factor is of course the air gap itself.

They have a fairly extensive classical and Jazz catalog, ranging from the big

Apt as always, Peter. But I was just talking about technical stuff.
Literature is even more fraught.
Back when I was a boy genius of literature...
[[[[Translation: when I was raw enough to say yes to all my publisher's
naff suggestions. Cf the present, in which I regard all editorial ideas
not originating chez Jute or another approved writer with dire
suspicion]]]]
....I was deeply flattered that a most prestigious publisher should offer
me the opportunity to translate a Japanese author whose name now escapes
me--he later committed public suicide in disgust at Japan's loss of
military fortitude. My own editor, when he heard of this scheme concocted
behind his back, said darkly, 'This will make a man of you. Or...'
Soon it became clear why. It was an impossible job. There was no singular
meaning to any sentence or phrase almost anywhere. When I tried to give the
job and the money back, I was told firmly to stick it out...
[[[[[Translation of context: Too dumb and too overawed to tell an icon of
my then new profession to stick it where it would hurt most, a mistake I
would not make much past my 25th birthday.]]]]]
.....and given four sets of notes by different hands to help me. They made
the job even more impossible (yeah, I know, a permanent state of death, as
John Gardner said), because every one of them suggested multiple
possibilities not yet on even my most extended list of vagaries.
When I discovered the 'notes' were in fact trial translations by four other
translators who had given up on the job, I gave it up, and kept the money
on the ground that I had been hustled by this grand old man of literature.
Someone else did in fact make a fine translation...
(Tr: it reads beautifully and convinces those who cannot read the original,
which in the view of some, including possibly Rick on his earlier
statements here, is all that can be hoped for)
....but I always read it with a wry smile and half a dozen variant
interpretations in the back of my mind.
(Tr: I don't believe a single word of it!*)
Andre 'Thank god I am not so poor I have to do Japanese translations!'
Jute, gaijin
PS: as I have just demonstrated, even English, a brutally blunt language in
the wrong hands or intentionally in competent hands, can hide more than it
exposes. And even a message that starts in English, never mind a
translation from Japanese *through Chinese*, is easily garbled when handed
on down a chain humans. Remember the infamous message received at HQ during
WW1:
'Send three-and-sixpence, we're going to a dance?'
It had started out as:
'Send reinforcements, we're going to advance.'
*This is not as off-topic as it seems. In music you know the interpretation
is right because of its emotional impact on you the listener and stuff the
composer if he doesn't like the rendition. Variant interpretations never
vary as widely as in literature (in my opinion anyway--I may have a biased
view because I am a writer rather than a musician); this may help. But even
in music there are hidden subtleties. Recently, at the premiere of John
Tavener's new SQ, which he told me specifically was performed to his
precise expectation, members of the Chilingirian, for whom it was written,
told me specifically how disappointed they were in the piece. They were as
amazed as I was (I too thought it a reprise of a pair of his earlier string
quartets and merely competent rather than great) to discover women in the
hardnosed first-night audience crying with emotion engendered by the piece.
But, unless you are a professional music critic, you should buy this SQ,
reviewed on my Disk of the Day netsite, when it appears on CD--it is
perfect tube amp music, warm and enveloping, with a strong, consistent
bass line in the cello part; pleasant listening and a test disk all in one.
As a side note, I recently sat next to Tavener at a less than perfect
performance of his choral Ikon of Light, and tears streamed down his face
from the emotional impact. Unlike all other composers and all the pro
musicians I know, he doesn't judge the performance but always reacts to the
meaning of the music; by contrast, the pianist Joanna MacGregor, a most
generous performer and person, also sitting with us, at times seemed
disapproving of the shortcomings of the performance, and went as far as to
raise an eyebrow when she caught my eye at the moment it became clear the
choir didn't have either the basses or the sopranos to do all the necessary
business.

If you are going to discuss things, you should first of all get your facts
straight: the above-quoted incident *NEVER* happened! Like almost all stories
of critical messages being botched in translation, this is yet another myth,
perhaps most perpetrated by those self appointed literary geniuses who are
unable or unwilling to actually research facts.
For whatever strange reason, society has a fascination with these sorts of
translation-gone-bad stories, yet the number of stories like these that are
actually verifiable truth is extrodinarily small! The fact of the matter is
that all human translators have a bare minimum "competence" that arises from
basic language knowledge (understanding!) that prevents these sorts of things
from happening. In fact, it has been demonstrated several times that even
relatively unskilled translators, with little more than the most basic
knowledge of the languages involved, simply will not make these sorts of
errors, even in idiomatic translations. The reason for this has to do with the
way we (humans) handle language; translation is not simply a "surface"
(syntactical) activity, and is thus largely immune to errors of apparent
synonyms, etc.
Although I'm not a translator (by any stretch of the imagination), I did study
this aspect of translation quite intensly with respect to natural language
processing in (so-called) "AI" systems; one consequence of the huge world
interest in automated translation systems was the realization that the problem
of translation is far deeper than originally hoped: translation of human
language brings with it many issues of semantics, interpretation, meaning, etc,
and is thus a Hard Problem. On the upside, though, it has been shown quite
conclusively that enormous translation errors such as quoted by Andre are
virtually impossible in a system with rudimentary language understanding.

One might have hoped, after I signalled with 'When I was a boy genius of
literature' that my intent was not literal but literary, that you would
pass this by, Frank, and save yourself the apoplectic fit, which can't be
good for you.
Your reply makes me wonder which version of my original message you read:
the one I wrote, or perhaps a computer translation? The style and content
of your reply makes my original point about the subtexts missed by machines
and naive translators with such force and perfection that there is nothing
I can usefully add.
Another cause for amazement is that a fellow as superbly informed as you
doesn't know that I wrote in an essay in Forum about a hundred years ago
that the 'advance-dance' incident never happened (of course I made my
point without the need for caps or italics).
Lighten up, man, or you'll keep on missing all the best jokes.

That article really bothered me. Sure the reference to 'armatures' and
the off-shore
source of tubes was noted but there was something else. The writer
compared the vintage designs in glowing tones with the run-of-the-mill
current machines with their black-on-black panels and bouncing LEDs. He
also says that all the design inspiration has been channelled into the
computer business.
Garbage! Computer esthetic design is bankrupt and looks more like mid-fi
boxes than anything else. Clearly, the writer has never been exposed to
real contemporary high-end designs which are the modern day equivalent of
the Marantz and Mac of the 50s and 60s.
What do you expect?

My understanding is that Majordomo (a Perl script) simply takes an incoming
message destined for JoeNet and sends it back out via sendmail (if in
unix) to all subscribed members. Problems can happen if your message header
is abnormal because Majordomo looks there for address information. IMHO
the "problem" is not Majordomo (it treats all email addresses in the same way)
but a link in the chain of servers between your machine and the JoeNet server.
The path a message takes to get to your ISP can vary wildly depending on how
busy a specific node is.
I occasionally get messages in batches too.

Stephen Lee

Yes, but your drawing shows the 5 volt winding, whereas I'm sure you
meant to draw the 6.3 volt winding. All this does is bring the
heaters to ground potential, insead of letting them "float".
Seems to me that 50k is a bit high.
> 2 Should I do this for 5vAC and
> 400Vac(~1M) as well?
No, it's not applicable to those windings. In addition, if you have
no center tap on the 400 volt winding, you'll need to use a full wave
bridge, or a half-wave rectifier.
I'm fond of full wave bridges into choke-input filters. This would
give you about 300-360 volts, depending upon the rectifiers used. I
would like to try this scheme using 4 TV damper tubes.

I'm trying to figure this out, Peter. If you mean a balance pot for the
6SN7 filaments, it's not necessary since they are indirectly heated and
filament noise should not be a problem. But if you have no CT on the 6.3
volt supply, just ground one side.

If you do not have a CT for your Hv supply (400V) then I *think* you must
use a bridge rectifier to create a positive and negative leg, then ground
the negative leg. No?
If the 5VAC is for a DHT tube, then you would want a 25-100 ohm balance pot
in series with the filaments. If it's for the rectifier, then you do NOT
want to ground this supply.
Does this answer your questions???

I went out to buy some 0,4mm copper wire today, for the chokes. It
turned out to be 0.38mm, since my supplier had a reel with 4 Kg left on
it, of that dimention. ( My supplier is NORDELEKTRO. They repair
electromotors, and service elevators, and such. Real good guys!)
I asked if they have some insulation paper, and got this reply: "Yes,
we`ve got this MYLAR foil". 2 Different thicknes`, I bought 200 grams of
0.12mm, That`s 5 thousands of an inch.
I know it is used for caparitors, as a dielectric.
It is also wonderfully stiff, which is an asset, when it comes to making
an even lay of the turns. (And it is transparent, so it looks good too!)
But is it any good in a transformer?
When I left the place with a big smile, I felt I had made a scoop,

Subject: Man, that's great bass!
Date: Mon, 14 Dec 1998 13:11:01 -0500
Source: Sound Digest Archive v01.n537
I've been following the "what is bass?" debate with great interest and a
fair amount of bewilderment. I'm having an interesting experience which
may or may not relate.
I recently purchased a portable CD player and headphones which I like
very much. The headphone is an Etymotic ER-4S, which is a
deep-in-the-ear style made by a company that makes earplugs designed for
musicians to block all frequencies equally, as well as some devices for
hearing-impaired folks.
The first thing you notice is that they go all the way inside your head
- - basically the only thing between these and your thoughts are your
eardrums! This has been the hardest part to get used to, but I have
gotten to the point that I don't really mind it.
The next thing you notice is the isolation from outside sound. It is
impressive, 23dB is claimed. I ride the NY subways, I can't really hear
the train noise well with them in. The result is that you don't really
have to play them too loud, there is essentially no noise floor for them
to compete with. I think this isolation effect is a big plus for the
sound, I guess it's easier to resolve low-level info against the quieter
background?
Another observation on the unusual quality of the bass - it is
much more damped I guess than anything I've ever heard, and there is no
visceral quality to it at all - the sound vibrates your eardrum only, no
chest kick or bone conduction as far as I can tell. Initially this
sounds anemic but I've come to appreciate the clarity of timbre down
through the low end which these phones exhibit. My wife hates them, and
says they sound "tinny" which is her catchall audio criticism.
Measured response is extremely flat : check
http://headroom.headphone.com/headphones/Etymotic.htm for more info on
these 'phones, and
http://headroom.headphone.com/technical/headphonenarrative.htm for some
graphs and comparisons to other headphones. Since using these phones I
think I have grown a little more sensitive to peaks and valleys in my
system response than before. One bit of commentary about that : one of
our listmembers mentioned once that whenever he is asked to tweak
anybody's system, invariably he just sets all the EQ flat, and it's
always a popular move. I have always done the same and so maybe I'm
responding to that in enjoying the sound of these phones.
I sprung for these (about 300 bucks, big coin for a guy who tosses
nickels around like they was manhole covers) because I thought it was
silly for me to be scarfing up CD's like there was no tomorrow when I
had such limited time to enjoy them at home. I have about a
40-minute-each-way commute, and I felt this investment would help me
enjoy it more. It has.
At least one other Etymotics owner is on the list; anybody else have
experience with these they'd like to share? Dave, these might be a fun
tool to use for checking a mix while the band blasts away, or they might
be a fun tool for preserving your hearing - just don't plug 'em in!
My title for this thread is a tribute to my friend Andrew, who has been
a working actor in NYC for about twenty-five years and made his Saturday
Night Live debut this weekend. Way to go Andrew!

Thanks also from me as well... After hearing about Mapleshade, I called and
spoke with Pierre Sprey and not only was he courteous, but he took the time to
share some studio construction (listening room) techniques with me as well.
(And this was right after his NPR interview when his phone was ringing off the
hook!)-- I ordered his blues releases & some jazz CD's, and look forward to
using them to help tune my room acoustics.

Great CD. These guys can do some very credible covers of Robert Johnson
songs. Why I'm cool: I bought my copy from Andrews when he was playing a
bar in Florida.
I don't know the following, but I like Hammiett Bluiett for more than his

two. I'll try them out, anyway.

Dear all,
For USA-living readers:
Just heard that today (Thursday, 15th October) on NPR's "All Things

Airs at 5pm Eastern. For anyone not familiar with the Positive Feedback
interview (sometime over the last year) or with his recordings: he's an
interesting chap specializing in analogue masters recorded in his living
room or in clubs/bars, mostly Jazz.
Forgive me if this was already announced on the recent Mapleshade thread.

Ed,
Purely technically the Marantz CD-57 is identical to the 67. The 67
differs in using an additional Buffer (HDAM - best bypassed) and in
having a optical Digital Output.
A few 'lytic Cap's have been uprated. The 67 SE adds more better Cap's
and an additional Bottom-Plate. That's all. Go for a 57 and do an
all-out mod using Black Gate Caps (F/FK Series in the analog Section and
PK Series in the Digital) with the Money saved...
An extensive Article on modding the 67 SE (by yours truely) is found at
www.tnt-audio.com. Look in the english Pages under "Tweakings"....

Hi all,
>what's so bad with the HDAM ?
Nothing. In a unit modded to my tweaks and described in TNT-Audio it is
not needed and ever so slightly reduces the absolute transparency.
Indeed, at the moment I have re-connected the HDAM with an slight
increase in "musicality" as I reverted to my "ultra-naked sound" Cables.
Most CD-'s I listen to (easy listening, pop and the like) are produced
way too bright, so HDAM helps...

Yes. Completly correct. But how does Marantz choose to use this Stage?
As Unity Gain Buffer following a Pair of NE5532 (actually the 67 uses
the NJM2114 - not a big step up anyway) in the Filter.
If you use the LM6172 to replace the 5532/2114 you will find the LM6172
to be the more capable Line-Driver and if it is in there already.... If
one where to replace the Op-Amp's with the OPA2604, I'd suggest keeping
the HDAM in Circuit.
In any case, I would not loose all that much sleep about the HDAM
Circuitry. It makes preciosly littel difference in my modded unit. If
you mod a 67 try with and without and see what you like better, if you
mod a 57, don't bother introducing it (the space on the Board exists and
the Service manual lists all Values and parts)....
Kind regards Thorsten.

Thorsten,
what's so bad with the HDAM ? I've seen the circuit in the "Musen
to Jikken" mag from Japan, and it looks as elaborated as a
modern amplifier stage can be, having all the modern tricks, and
reminded me a bit of what I know about the Connoiseur/Lyra preamp from

The CD 67 has a 2-Layer Bord with an almost full groundplane. There are
a few small Areas (but larger than for simple Pin-Clearance) unfilled,
but I'd expect that.
While the basic technology platform is fairly outdated (the NPC SM5872
was not SOTA when it was introduced and that was a few years ago) the
Execution of this is fairly decent.
Otherwise there is no way that I could get away with such relativly
small mod's for such a good effect. This weekend we will test the
Marantz against a Audio Sythesis DAX (Ultra Analog DAC Chips, HDCD....)
and I'm quite interested how this will go....

Well, I decided to switch to a good deal of hard-wiring with Belden
Miniature Teflon Coax for anything that natters (like Digital Signals).
It does not look pretty but is very efficent at cutting down noise and
jitter....

Thorsten,
Just curious but I was wondering if these Marantz players you mod have two
layer PCBs with full ground planes or if they still make do with little
ground traces running here and there and everywhere? A customer recently
sent me the schematics and PCB layouts for his Japanese player asking for
help with a S/PDIF output mod. I was reminded and horrified all over again
about the compromise typically make in doing without a full ground plane.
It was SO ugly with power supply grounds running on skinny traces between
signal lines and noisy digital chips with no ground plane in sight.
Of course PCB layout is one of my passions and it was the control of those
things that drove me from modding players to designing my own DACs. Some of
the Guild members are taking it even further graduating to 4 layer boards
to get things even quieter.

Which is not bad as long as the implementation is properly done otherwise
you throw the child with the badwater
Even cheapo Philips players (like CD130) use double layers !
My coniction still is that you need 4-layers in order to meet the (my)
jitter specification

Better Idea. Try the LM6172 from National Semiconductor. More expensive
yes,
but MUCH better sound. BTW, you are talking about the opamps not the DAC.
Also, do bypass (remove) the Output Cap's. In the SE-Version they are Elna
"Silmic" Cap's, which can usefully replace the PSU-Cap's on the HDAM Amps
(the little copper Boxes).
I also removed the Muting Transistors (two per channel - near the
RCA-Output
Jacks) and put some nice RCA-Jacks in (WBT look-alikes with Teflon
Isolation
for about 3 bucks each)..

Easier and better, there are many parts of the units chassis where
self-adheasive
Bitumen Mat's can be used. As I had the SE-Version (worth the Money if You
have not got access to a suitable metal-workshop) I put one layer directly
inbetween the additional Bottom-Plate and the Chassis. I also almost
covered
the inside of the Hood and much of the chassis inside. I also damped parts
of
the Transport similar to the previous post.
All of that pretty much applies to all kind's of Budget CD-Players.
I feel that all these mod's are easy to do and give a big improvement.
You can e-mail me if You want all the dirty details how to go much
further.

Hi All,
Finally after a couple of mixups, I got my CD-63 yesterday from Audio Advisor.
Earlier they had to back order and then shipped a CC65 (changer) by mistake.
Mine looks to be in new condition and I can't find any problems with it so far.
I have compared the transport to my old Sony and it beats it hands down in sound
and build quality which is really what I wanted. And it looks real nice to boot.
I have compared the internal DA and analog section to my AA DTI+ and DDE 1.1
and it is pretty close but lacks the last bit of resolution in comparison, but the
musicality is still there. It is probably due to effects of the DTI which lowers jitter
significantly. All in all a very nice looking and sounding unit.
I feel that it is a good value and unless some problems crop up, I am well
satisfied.
I'll try the damping sheets on the transport and report back.
IMHO, a good CD player for $200.
FYI,

the dealers with problems ( warranty ) . They were factory repaired.
Only two small problems , The machines were not sent to the Marantz factory,
they were repaired by a shop that bid the job and got the contract . It gets

Hi Bill,
I appreciate your info on the CD-63 sale units and also your feelings on this deal.
I wasn't told about this when I placed my order and initially had some misgivings about it
after I read your post.
So I talked to Ken at AA today and he said HE had not had any come back yet and
that these are repaired, defective out-of-the-box, new units with no use.
I will have 30 days, no-questions-asked, to return it for any reason, and a full year to get
repairs or replacement if needed. I will definately check it out thoroughly and bail out
of the deal if things don't look right.
I have researched used ones on the net and the price is reasonable, especially if it
is in new condition.
On the plus side, the CD-63 can be tweaked extensively and also has a lot to
recommend it above a standard "mid-fi" unit. The Phillips CDM-12 transport and
TDA-7345 decoder it uses is supposed to be a good one. The Delta-Sigma DAC on
the later models (which this is) is a Crystal 4303, which is a really nice sounding DAC
(I have one in my AA DDE 1.1). The analogue section (HDAM) is also engineered to be
a cut above.
This unit and it's cousins (CD-63SE, K1, etc.) have a real cult following which I think
must be somewhat deserved. I still see want ads for people seeking used ones on
the net.
After pondering this overnight, I've decided that for $199, which ain't much these days,
I'm still gonna take the gamble and see if I can get a good one to play with. And after
reading Torsten's tweak list, I chompin' at the bit to get at it.
I'll let y'all know how this comes out.
Usually lucky, ; ^ )

Yeah, not bad at all, for $200, I'd say very good. Beef up the chassis like
they do on the SE, (read Thorsten's posts on Marantz CD mods) and it will
be better. I've A/B'd the 63 vs. 63SE, and some other, fancy transports all
in one shot, and the SE was definitely closer to the sound of the better
transports than the 63.
For some odd reason I've had the best luck with a mundane Monster Cable
digital cable with a snap on choke on the DAC end with this setup (into an
X-DAC, natch).
I'm finally going to put in the green diodes around the transport and some
shielding and other stuff to mine. Was waiting for the warantee to
expire...

Tell us how it works out. I'm these days on to other projects and the
seedee player sounds niche enough to leave the soldering Iron off it.

Hi All,
This same subject was discussed over on RAT just a few days ago. I
forget who was commenting, but he concurred with Guido that the CD-63
transport is a piece-of-shit, mechanically speaking, and recommended a
couple of others. Since that was only a few days ago, I am sure
that (those) posting(s) are still available, if anyone is interested.
I also am interested in this subject, as I, hopefully, will soon be

That may be the case but each to his own.
I have a 63 and compared to other transports I could try here it sounded
the best, perhaps of a bad lot.
Mods are to be done though, to try to enhance the performance.
Check at www.tnt-audio.com/clinica/cd67.html for details and for mods
considered.

Well mechanically spoken it's not a TEAC or so, but the jitter is not due
to the mechanics. It's electronics that can be made better (not for $199 I
suppose)
Unless you are very handy, and know were to start, you may better buy a
more expensive transport. The Micro Mega is not bad either

Hi Doc,
I am extremely interested to find that your hear noticeable differences with various transports into
an X-DAC.
I thought the philosophy behind the X-DAC was to make transport differences largely irrelevant by el
iminating this source of jitter?
If you get 0's and 1's without timing errors, it's perfect isn't it?? :-)
A cheapy computer transport doesn't lose or add any digits.
Cheers,
Bart - Sony 557ESD transport user standing back.

Yeah, not bad at all, for $200, I'd say very good. Beef up the chassis like
they do on the SE, (read Thorsten's posts on Marantz CD mods) and it will
be better. I've A/B'd the 63 vs. 63SE, and some other, fancy transports all
in one shot, and the SE was definitely closer to the sound of the better
transports than the 63.
For some odd reason I've had the best luck with a mundane Monster Cable
digital cable with a snap on choke on the DAC end with this setup (into an
X-DAC, natch).
I'm finally going to put in the green diodes around the transport and some
shielding and other stuff to mine. Was waiting for the warantee to

Hi again,
Thanks to all who replied to my CD-63 inquiry.
I decided for $199 it was a good bet for a decent cheap CD player/transport,
so I sprang for it.
I had been considering maybe spending $500-1000 on a good transport but
naaaaa......That would take funds away from more important things
like CDs, LPs, caps, tubes, etc.
My old Sony CDP-209ES is going on 8 years old now, so I'm gonna try this
one out as a DIY transport replacement.
Thorsten's Loesch's website at: http://www.tnt-audio.com/clinica/cd67.html
has enough tweeks for this one to keep me occupied for years. Thanks Thorsten.
Might tweek it some in the deadening department with dflex pads to start with and
see how it goes.
I'll report back when I get it.
Thanks again,
- Ralph

Thorsten.
I've just finished (almost) with my CD player... implementing my variations
on Thorstens mods... the main differences being:
1) 10,000uF of reservoir per voltage
2) 6,000uF after the 12V regulators.... Elna Silmic.
3) 16Mhz Crystal is mounted on rubber with flexible leads going to the
board.
4) A display off switch (for my own convenience since it sleeps in the same
room as i do)
5) The PCB is now mounted on leaf type springs ala NAIM.
6) The digital outs are disabled as is the headphone circuit.
7) Seperate DAC PSU
8) Offboard twin transformers (Analog and digital)
>Might tweek it some in the deadening department with dflex pads to start

>see how it goes.
Do the deadening first... huge difference.. then get in there with the
soldering iron! You'll be able to ignore half of the mods as you dont need
to worry about the analogue side. Then sort out the digital PSU with the
inductors and caps that Thorsten has recommended.
Also.. I removed the dig outs on my player as I dont need them and i wanted
to pull the circuitboard away from the back of the case... I actually did
perceive a *slight* improvement by removing the outputs (and all their
circuitry) Perhaps this could be down to the fact that the LED may pollute
the power line.... any thoughts anyone? Anyway, I humbly suggest removing
whichever output you're not going to use.
Ever thought about making a different case for the transport? Perhaps a
heavyweight concete case, lined inside with copper sheeting, and with a nice
wwod finish? All mounted on some blobs of sorbothane?
Anyway, have fun, and as I've found out, the 63 has a lot more life left in
it than most people think!

Indeed. I have a CD-53 that I have implemented the first half or so of
Thorsten's mods to. Sounds terrific and is very impressive indeed.
I removed the output capacitors, replacing filter caps with
silver-mica, beefed up power supply, extra bypass caps over the
(replaced) op-amps and cabinet dampening (a whole bunch of that
car-audio door-damping stuff that comes on a roll and you put on with a
heatgun - can't remember the name of it just now but you all know what
I'm talking about).
This series of modifications turns an ok player into a very enjoyable
and lively performer. Great microdynamics and detail, lots of speed (a
la Linn's infamous "pace") and very good bass.
These units have lots of potential. $US 199 for a new CD-63 is a great
place to start.
best regards,
Aaron

Dunno 'bout this, but I keep a 50Ohm Network Terminator on the BNC which
I substituted for the RCA Digital Output. Notable Improvement.....

I use 75 ohm for years, it helps little but more improvement can be made,
the digital electronics are not of that good engineering
It also helps to stop the display running. Very often the segments are
multiplexed with ........ a few kilo Hertz.

Well,
I'll but both my "idiot!" questions in one post:
stupid question #1 - what is "sp#14" ?
(it seems to be a magazine and the exitement is palpable when it arrives)
stupid question #2 - what's the basic difference between the 63 & 67
(the tnt page comments on the similarities, but not the differences.
Does the 67 solve the jitter issue?)
There's a 63SE for sale near by for 1/2 list price.

Comrade used to hang around the pub* (*...saloon bar). He really enjoyed
it when the young gentlemen on their big noisy motorcycles rolled in.
They were so sociable and jovial. They also appealed to Comrade's sense
of sanitation and ecology, with their shining and immaculate
two-cylinder machines, their ecological choice of all leather clothing,
keeping the sand and grit off every part of their bodies with heavy
leather attire, and never smiling so as to keep insects from their
teeth. They drank alcohol regularly, in Comrade's Russian fashion, to
keep their internal organs sterile. And due to their considerate nature
they always retired to the toilets to smoke. Unfortunately, diabetes
seemed to be rife amongst the group, and Comrade noticed with approval
their consideration for the squeamish in always retiring to the toilets
to administer their insulin.
Comrade needed to learn English language, so he would spend a great deal
of time at the pub, listening quietly to the banter of his newfound
friends, never intruding, but he learned quickly as he was no fool. Soon
he understood almost everything they said, but there was one frequently
used term that made no sense. Whenever spoken, this term would cause
general excitement and animation, and Comrade sensed their increased
bonding as a group at these times. He had to know what it meant. It was
time to speak. Mentally marshaling his new vocabulary, Comrade pieced
together his request in the clearest and most unmistakable terms; he
said:
"So, f***wits, what's this piece-of-sh*t HOG thing?"
May he rest in peace.

Confession time: (Bless me father....) I presumed SP was "Sound Practices"
as mentioned on Lynn O's pages. What I don't know is: what is the

interest to someone marooned in deepest, darkest West Oz; what
its subscription/delivery rates are; or how to subscribe.

Subject: Marantz CD-63 as a transport
Hi All,
Does anyone have an opinion as to whether the Marantz CD-63 is decent as a CD
transport ?
Audio Advisor has B stock units on closeout for $199. I was thinking about getting
one.
Any opinions appreciated.

In May, Scott Grammer described a tube crossover project using only (8) 5687's.
I am interested in finding out how it went. Perhaps Scott can provide us a
report?

I can give you some details now:
Tube complement:
8 5687's
1 5AR4
1 6AS7G
2 0A2
Power supply 300V tube regulated @ 200mA, predicted ripple on 300V line
<50mVrms. 12VDC SS regulated @ 4A, predicted ripple on 12V line <1mVrms.
Xover frequencies 400 & 4k Hz.
Gain variable from -6dB to unity, per owners' request. Max in/out
10Vrms. Predicted distortion at 1 v out <0.1%.
Predicted S/N (If I get all the grounds right! :-]) >90dB unweighted re
1v out.
All class A, SE, no NFB loops. Cathode follower outs. 330k input Z.
Cheers!

It's still in progress, mainly due to personal and familial problems
which have monopolized my time over the last few months. I haven't had a
lot of time for bench work. I do have the chassis completed, the power
supply up and running (Shunt regulated with big power resistor and
6AS7G, unig 0A2's for reference, and zener referenced series transistor
regulated 16V filament supply, then a power resistor and cap to provide
slow turn on and exactly 12.6V at the tube sockets. With all the tubes
in place the ripple on the 12.6V line is less than 0.5mV!) and about
half the audio circuits built. I had to enlist a bit of help with the
passiver crossover filters, which were a bear, but they are designed and
check out ok mathmatically, I hope they will measure as well. 5687's are
such cool tubes! I just hope Dave (the fellow I'm building this for) can
hold out a bit longer.
Cheers!

Hello everyone....just finsihed up a brand spanking new plate choke....even
Saddam would like this one.....
It is a twin coil choke with the following specs
Series connection: 10 madc @ 600 henries DCR of 1125 ohms
parallel connection: 20 madc @ 150 henries DCR of 562.5 ohms
these are housed in a custom made solid brass channel frame (the largest size
channel frame made)....but still physically manageable in size....
price is $99 each.
email me privately if you need more info....

Oooops. late at night....let's see if I can do some simple arthmetic...thanks
guys for pointing out the error.....
each section (and there are two separate winding sections) have a DCR of 1125
ohms.
In series (adding) the combined resistances would be 2250 ohms....at the rated
10 madc of plate current we could then expect a voltage drop of 22.5 volts.
the L produced will be 600 henries.
In parallel connection....the combined DCR should be 562.5 ohms.....at the
rated 20 mils of DC plate current the expected voltage drop would then be
11.25 volts....The L expected would decrease to 150 henries...since we cut the
turns in half we should expect only one quarter of the inductance.....
now...I hope I got this right...off to beddy bye I go.....

Joes: Still cleaning out the basement...here is something I found three
of....
A potted power transformer made by Electronic Research Associates Inc.
model number CV300
serial numbered
input 115V@60cps
output 300V@20ma
has four terminals on bottom...unit is hermetically sealed....painted gray...
footprint is 2.5" by 3" and the unit stands 4.25" tall.
have three....asking $75 for a pair of these plus shipping
and for the remaining unit only $25 plus shipping...the single unit should
work well if you wanted to build a line level only stereo preamp with medium
mu triodes running less than 10 mils each.
No foreign sales please....

As the Ariels move closer to production, I am thinking about a different
style of construction to act as divider between the top and bottom midbass
drivers. Take a look at:
http://www.teleport.com/~lynno/Ariel-3.gif
and see what you think. All of the internal pieces slot at 90 degrees into
router-cut grooves in the sidewalls, avoiding the tricky mounting of the
slant divider panel in the current design. In addition, the transition
between the TL and the labyrinth portion is much smoother.
The non-90-degree joins inside the cabinets are filled with putty or wood
filler, to avoid buzzes or air leaks. The rigidity comes from the
side-to-side bulkhead construction where the internal plywood pieces act to
stiffen the sidewalls of the cab
