Jessie, sorry to hear about this trouble. Another thing worth knowing is that Teflon notoriously "cold forms", meaning it shifts shape over time according to ???, even when "not hot".Best regards,Paul S...

The ultimate turntable would have a very light platter that allows a teflon bearing without too much wear off and a DSP-controlled piezo motor that can introduce arbitrary speed deviations to overlay the speed irregularities of tape recorders and cut...

it is worth reiterating in this thread -- and perhaps Romy should update his advice in the relevant section -- that exotic japanese teflon sockets such as the one made by yamamoto soundcraft are no good for the 6c33c, whether because of insufficient ...

Romy,
I noticed in several photographs of the various Melqs that you are using the Hal-O dampers on your driver tubes and sometimes on the regulators. The ones in your pictures are the earlier versions of Herbeleins' products with the thick polymer...

Well, I can't support the statement, that these sockets are bad.I changed 2,5 years ago to Teflon sockets, use my ML2.1 a few times a week, on weekends it is running the whole day...and never have/had any problems.Maybe there are different Qualities ...

Chris VenHaus comments, "The original production TFTF's are still fine at 600V, including the older, larger values over 0.47 uF (that were subsequently de-rated to 300V for NEW production). It was only when the NEW DuPont Teflon was...

Hi,[quote user="Romy the Cat"] After some experiments and still being dissatisfied with the HF I ended up consulting with Dima. He spread me a theory according to which the HF was killed by my coupling Silver Mica cap. All my arguments that sil...

You might try these: http://www.goodsoundclub.com/Forums/ShowPost.aspx?postID=1093#1093Still, I think Yamamoto sockets shell be fine. The material of the sockets base – would it be Teflon or anything else is less relevant. You need to wary about the ...

I know it is a trivial point, but I dislike the whiteness of valve sockets. Since neither teflon nor ceramic is easily painted I have mine covered in black nomex fabric. This is no good for the 6c33c, of course, as it needs all the breathing spac...

Romy,My DSET amps are still open (no top plate) so are fully ventilated, but I have left vents in the top plate around all of the valves and installed two computer fans (running very low speed) that push air from the bottom and out the vents on the t...

What problems with the Johnson sockets are these trying to solve, again? Would they really be better overall than a lower mass design along with chassis through-holes, like the ML2, etc.? If a reader is using these, do they appear to better stabiliz...

A bit of search and it turns out that VPI and Simon York use something more sophisticated than RCA on their tonearms: they use Lemo connectors...and immediately fuck everything upby connecting it to their "RCA connection box", right next to the arm H...

The "lack" of HF is definitely one of the wonderful things that makes one think of spending 30K on a phono stage. Glad to hear you are "suffering" a similar "dirth" of HF [noise] with your DIY corrector.I wasn't going to say anything, but I won...
|
|
Yes, this is what I meant: link the pins using heatpipes to a heat exchanger, in fact I wonder if one could use the heatpipes as the filament conductors direct.The yamamotos are beautifully made but badly designed. The receptacle of each pin is a spl...

On its great majority, I share your opinion about reviewers and the audio industry goals and means. That's why I don't give a damn about their articles, but it's just entertainment reading them. Have you tried teflon tape wraped around the tonearm's ...

Here's a start on teflon sockets I had bookmarked for some reason:

Just saw these on the Stereophile cheap ads page.http://www.audience-av.com/capacitors/t_description.phpI have used the AuriCap and it is OK, if you have to have a cap.I have not tried these new Teflons, and I did not try to find the not-plainly-post...

Recently there is a lot of talk amond the audio hoodlums about the reported benefits of the V-Caps capacitors.
http://v-cap.com
They have good press and good feedback from DIYer and manufactures, the web sites that sell them push the “right button...

Like Romy said, the best route is something that's actually, practically useful and sustainable. I use Onix parts (also labeled NeoTech), and there is also FuruTech, and a couple of others. I think I gave you links to Chris VenHaus (US; he's also t...

Dear Romy,Thanks a lot, I've forwarded to him your answers, let's see what he says. I have tried Mundorfs in some critical places in the integrated tube amp I'm using now and they are pretty good, expensive, but not at the level of those Auricaps, Ho...

Wow, you sure do pack it in there! I like the way you silicone the caps and other things into place. Maybe you can do the same for the bleeder resistors and wiring bundles? That is, once you are sure it is operational. Wires c...
|
|
Jessie, congrats on the new *TEFLON* sockets. Did you do the cap shuffle, too, while you were at it? And what's this you say; you had to mill the sockets (or the chassis) to get them to fit? Tres droll!Now that your operating points are stable you...

I have some ZVN0545A mosfets here for exactly that purpose of replacing cathode followers. You may like to try this starting at 2mA (250V supply, 125k biasing resistor). Did you or Dima try Soviet SSG silver-mica for the first coupler? I am using 0.1...

|
Well, Kevin Carter says he's had no trouble with his own Big Cardas parafeed caps, and his caps have been in service for 3 years. He did not say anything about anyone else, but he did suggest there are plenty of other likely susp...

These look like the absurdly expensive Yamamoto soundcraft teflon version, which I have used, and which do not work because the receptacles for the pins are shaped so that there is only a single point of contact when the pins go in. So the heaters pe...

Hello everyone,This seems like the place where the 6C33C experts hang out so I figured I'd ask my question here.I'm currently collecting parts to build my very own 6C33C amplifier, and I had bought some of the cheap chinese sockets for it and thought...

chaps,I found the design details; it was posted by on the Joenet a few years ago.Basically, it involved making a vertically sectioned bobbin; start with a 70mm diameter cylinder of whatever material (I used white nylon cos it was available and cheap;...

[quote user="Paul S"] God, this sounds like the very worst sort of DIY threads! FYI, I HATE DIY![/quote]It sounds but it does not necessarily mean that it is :) Let me try to deffend a bit my last postings:DIY is a self propelled random walk "let's ...

I would like to point out to a very important moment that took place in here. I do presume that Jessie account is very accurate and the Teflon sockets were bad. I even presume that they were bad not only from the perspective of cooling but were bad s...

I have run each of these for long periods and can validly comment.My power amp circuitry is a 6N1 based Mu Follower driving a 2A3 in turn driving a 3K Tamura amorphous core OPT.The 6N1 tube is a special military type that is not freely available.Ther...
