It is nice to see the de-centresation of audio manufacturing. Formerly US, UK, Germany, France, a few Scandinavians and off the wall Japanese were making high-end audio. Today the lead positions in interesting high-end audio have moved to Poland...

[quote user="Paul S"] Which caps exactly did you decide to try? I don't recognize the big black jobbies. Are they oilers? Are they 200V? [/quote]
I did not “decide” but went with what I had in my hands. They are the Ansars from the...

[quote user="Romy the Cat"]Make the full-range and then you will see where you are.
Still, I feel that for MF channels it is beneficial for do with a good DHT output
stage instead of 6C33C and perhaps it is a good idea to use DHT driver as well.

A few days back I posted the following post:

…proposing the parties of interest to play along in Milq vs. DHT competition. This interst derives from the following thread:

Are any who made high-gain phonostages dealt with vibration damping tube sockets? Since I’m thinking not about my next generation of 85dB gain two-stages phonocorrector:

[/quote]OK, now, after mach thinking, consulting and very little actual listening I have finally conceptualized my next move with powering Macondo MF channel. Considering that I have some extra space Melquiades’ ...

Last nigh I spend a couple hours to listening this thing. Since the amp is done in design phase and the final parts are still in order I can not finish it and close up – it kind of frustrating… Still, it gives opportunities to listen it knowing that ...

I did an interesting experiment today trying to learn if those Melquiades driver tubes have even gain. The Russian tubes are notorious to have very widely spreading specification, so….
I took 14 6E6P. Some of then were new, some used and some violen...

[quote user="hagtech"]Note the '63 has much higher gain. The horizontal spacing is basically "mu". Interestingly, the 6e6p has lower gain than both of these. To me, the curves are beautiful. Spacing is relatively constant, ind...

[quote user="nl"] I have used Russian high-gm tubes like 6C45 in amps before, including single-stage designs very much like Romy's single-stage Milq. These have many attractions. However, in my experience it just didn't have the tone. Jim de Kort of ...

[quote user="Paul S"] This may also be a factor in the "randomness" capability, which is really only freedom of movement, and not "randomness", per se.[/quote]
OK, is it “randomness” of “freedom of movement”, the question is not about juts semantics...

Dear Romy, thank you so very much for mentioning our amplifier to your excellent forum. Indeed, during the last 5-6 years there are a lot of manufacturers “from non traditional hi-fi manufacturing countries”. In particular, in poor old Greece we ...

I usually do not cruse across DIY forums unless someone folks about me. Here it was - at some Russian DIY site they translated my article “6C33C survival guide” that made me to see what they have in there. One article from their site attracted my...

Frank Blöhbaum, from Sweden I believe, have designed for Thorens a preamp that I think the first outside of Russia commercial use my 6E5P tube.

As much I did not answer back then as much I do not have it
now. The gas tube I never changed. Well, as I moved out of city in 2010 I did changed
them but not because I need but because I was “reviewing” the system sort of
speaking. The 12AX7 in p...

Something had changed very positively with multi-amping. I am not quite sure if it is because the full multi-amping of the specific of the implementation but it is what it is. The entire dynamic relationship between volume of a given tone and the ton...

[quote user="anthony"]My interest is
mainly in the 10Y/801A/VT25 tubes on one hand and the 45 on the other hand.
The YO186 also interests me a lot especially after reading your
impressions of it in your circuit and system, but it is a very diffic...

Romy, thank-you for your help so far. Unfortunately I now have some more hopefully simple questions regarding the "pre-final" schematic from your "6 Channel
Melquiades" thread (see below). 1.
Do you have a “final version” of the
schematic any...

user="anthony"]I have secured a couple of pair of YO186 and some
1940's Sylvania 45's to play with. I wish the YO186 were easier to come

capabilities of the tube ...

[quote user="anthony"]Do you have a
“final version” of the schematic anywhere? [/quote] I think that the one you
have might be recognized as final. The Rev2 was without DHT in MF and Rev3 was
with it. I did not do anything else with the amp af...
