[quote user="anthony"]...you've got me thinking about this now. I'll talk to some people here and see what they think, but it should be easy enough to place a shield between the OPT's and the tube bases.Thanks for bringing it up. I am looking for o...

Romy says:[quote]The problem is that in context of those amplifiers the COST BECOMES THE MAJOR DESIGN IMPEDIMENT[/quote]Yes, but it shouldn't -- should it?Let's be reasonable (a tall order). Either a designer knows how to design or not. If he doesn;t...

I have to tell you something: I do not believe to audio people. Whatever they say has some freakish twist of desire to present the sings in a certain way instead of witnessing and experiencing the thighs as they are. This is one of the reasons why I ...

Nope, the Russian tubes generally much, in fact much worse than western equivalents. There were however some exceptions. Those options were due to various reasons. The tubes like GM70, YO186, 1P24B, 6E5P, 6N30P, BO188, GM57, UB180, 6C33C, 6N6P, M...

[quote user="Romy the Cat"]There are no good ready to go transformer for 6C33C. Tangos are garbage. The 20 years back Tangos were OK for small tubes but Tango is long gone and whatever crap they label by Tango in fact Chinese transformers agglomerat...

[quote user="haralanov"] According to a friend of mine, who has a lot of experience with GM70, this tube starts to sing only with (very high quality) interstage transformer coupling. He told me that when it is used with coupling capacitor (as is the ...

You are correct about the load matching, for the Super Mild LF channel a half-Ohm of loading change bass quite dramatically. Still, the idea was to make this SET completely without any intentionally implemented feedback. It is juts not necessar...

[quote user="KOTriode"] On dynamic, the 6C33C tube showed its ability to go deep in the bass on Ray Brown trio recording of Soular Energy which is excellent for a 15W SE , the 845 amp can do better, but not by much, but probably because of its 25W ou...

[quote user="op.9"]A 20w tripath and a 5w El84 set per channel is a sensible and cheap combination. The tripath and line level crossover section could be thrown in for free![/quote]
Ah, the EL84! That brings so many memories…. I was 9-10 years old a...

...we'll have to compromise somewhere. So, since it isn't the spkr's range, then it must be the amplifier. Forget the ML's 18W. We must have ~38-40, so let's say our machine is using a 45 / 211 / 610 /g70 type of tube.Also I don't suggest we conclude...

[quote user="HookEm"]The reproduction does not seem natural... too far away from what I would hear at a live event (e.g., female vocalist). Sort of bright and fatiguing at times. I may not be using the proper terminology to describe it, but I do...

Frankly speaking I kind of thankfully drifting away from observing what is going on in the industry and particularly in amplifiers. Since 1998-99 I was using explicitly Lamm amplifiers that were heads and shoulder more interesting then anything else ...

I keep receiving emails from visitors asking me about my views regarding the GM70 vs. 6C33C. I am clearly not in a position to provide any EXPERT opinion because of two reasons. First, I never had a properly built GM70 in my disposal. Second, I ...

RLRB,
theecc81 is basically
the same tube with slightly less gain, if I remember correctly. It is not the problem
in your question, the problem, in my view is in different domain. You said: “idea
is to use input and xover tubes with ecc83 and rep...

[quote user="Romy the Cat"] It is in a way ridicules. For years people who build of use horn fight with honk in horn, particularly in midbass-upperbass-lowerMF horns. I built my midbass horns and it has no honk, I mean no honk ever of any kind. S...

Well, they do make an amp around GM100 and that is not bad.
http://www.etheraudio.net/abbssolute-intuition-by-etheraudio/
They get out of it GM100 30W. Well, if they get 30W out of GM100
then they use it at very low voltage and they driv...

Among many outrages foolishness that are so common among the people who going high-end audio one of the most ridicules is use of Single-Ended Triodes and low sensitivity speakers. The people who have db-meters between their ears instead of brain are ...

After a month of listening exclusively Melquiades and decided yestoday re-switch everything and to play Lamm’s ML2.
I was quite shocked with the result and I did not anticipate the ML2 could be so way off. I will not elaborate about the a...

[quote user="floobydust"] Some very good points here... if I downloaded the correct schematic from your site for the 6-channel Melq amp (also has the term DSET in the title) then you have created a 6-channel SET amp with built-in crossover points. Yo...

Interesting….. It is interesting to think about the relational of Melquiades slow take-up. I think that major contributing factor is that guy who calls himself Romy the Cat. Really, I think it’s it. The people who are capable to build amplifiers more...

I need to give it to you and I need to retract my comments
about your bass pipes. I did find them to be ugly in your prototype drowning
but assembled I find them look very present, in fact quite wonderful. Connection al, of then in parallel is goo...

This mooring I decided to play with my infinite baffle. The
