Yes, my friends called me that too, but hey, I can't help it, my curiosity on tube amp get the best part of me, plus I can't build enough power amp to power all my 3 tri-amp system. I collect all kind of transformer, just for the 845, I tried about 6...

[quote user="Dominic"]I'm liking lately the idea of getting a chinese 845 based SET off ebay. Point to point(less fiddly modification), there's a choke coupled one available now, umm, 10 or so watts for under a thousand dollars, you know that sort of...

HookEm, I could only advised you on methodological aspect as I do not extend any recommendations about purchasing decisions. The 17x15 x11 is a very large room for a single driver speaker. If you insist to use a single driver speaker then get whatev...

Hi Romy,Interesting scale you've come up with there. I would like you to take a look at a preamplifier from Korea called Silvaweld. I have found that with this preamp (model SWC 1000) in my system I can differentiate easily the ...

[quote user="KOTriode"] With 6C33C output run at 40W plate dissipation, this amp run much hotter than an 845 amp with output tube running at 100W. I measured the hottest point on the bulb and it is about 380F. I guess the due to short bottle , 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 ...

As to the best transformers souding more transparent than the best resistors, I'll believe it when I (don't?) hear it. You claim to have heard this but I most certainly haven't. Based on theoretical arguments the noninductive metal film r...

i had browser issues again so some of the eloquence of my intended post will likely be lost.
anyhoo.
Maybe it's just me, but i'm almost never content with replacing what i've got with something equivalent. This would be as regards Greg's last p...

Thanks for all the suggestions. As it happens, there were no exhibitors at the Flemings Hotel this year. But I did pop into the Stax stall before listening to anything else.In general, I was pretty disappointed with what I heard. Most of the ‘convent...

Why use the GM70 apart from its power potential? For one thing, it seems to require literally lethal voltages to become remotely listenable. Is it really "that" linear, to insist on it?But my experience with GM70 is quite imited. I ...

Of course this is basically propaganda. Who argues otherwise? However, I have found that it is possible at times to glean a modicum of useful information from "reviews" like this via a careful reading of what is said and somtimes via...

Moreart, somebody sent me this link last year. You are surely the DIY pioneer of back loaded Manger.As you probably know this is a touchy speaker to work with. Rated at 91 dB/W input by the factory, we measure ~91 up to near 92 dB/1W/1m in our two mo...

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...

For me the "delta" with the newer Hal-O dampers was in the direction of increased clarity. One example is in vocals, where consonant sounds like "f" and "th" were much more realistic (my "s" and "sh" were already pretty good.) Beyond these typically...

Thank you for your answer.If I understand well, In purpose to do something realistic and good sounding. I should use at least 2 amplifiers (one for high frequencies and the GM-100 amp for low frequencies) with a tubes active filter at the inputs of e...

Hi,[quote user="morricab"]Thanks for the info about transformers. It is as I expected, however, that these passive devices are not passive sonically at all. I agree with you that the higher quality of the transformers should lessen the effects ...

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...

Decoud,
There is a lot of information on the subject of architectural horn design on this site. I would advise you to read older posts, use search. You might start from this one:

[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...

I do not think so. I would not present myself as some kind of specials in feline behavior but I think...

Well, in context of a full-range speaker, like largest Wilsons or the similar, the answer would be unquestionably no. Even if we biamp those speakers then the LF still is too wide bandwidth and too geographically bind to the MF section. The wor...

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 ...

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 ...

[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...
