[quote user="cat"]Will your tracer be able to pump 250-300mA at 230V? Will it be able to supple up to 100-110V of bias?[/quote]Not quite. I designed it for preamp tubes. But then I realized I could push it to cover a lot of the more popul...

This Sakuma’s is kind of BS. What I mean is that it has the appeal to be “good thinking” but only in the realm of marketing hype, something that the editor of “Direct Heating” had created around Sakuma. The reality is that the Sakuma’s TWO channel Am...

And I do not mean this as a criticism.I had for some time an "original" Music Reference RM9, which was made by another well-educated genius, Roger Modjeski. The RM9 was AB PP with adjustable bias and feedback/gain, with 6DJ8 drivers and a ...

[quote user="Paul S"]and dm did say he's tried (and rejected?) several SETs already, in the context of Klipsch Horns.[/quote]No, I didn't say that at all. I said that the were aspects of the 6C33CB's presentation via the Almarro A318B SET, that ...

[quote user="Romy the Cat"]It is unquestionably an ambiguous project. The topmost question that I would ask myself after this project would be the following: can Milq-biased 6E5P to be as good (sound-wise) DC driver as some vintage direct heated tube...

With regards to the links, as it happens, I totally agree that 15in Tannoy Reds struggle to handle complex music. The crossover is too simplistic and the cones too hard to control with a low power amp. Reds can be lovely in a simple vintage system bu...

Hi,[quote user="morricab"]Hmmm....I guess I can't really see that unless you are enjoying a particular coloration you are getting from the TVC.[/quote] Nope. On this you are wrong. Based on direct bypass tests the TVC's I USE (that is the specif...

I think the usage of Romys Injection Channel has misguided you to think it was implemented because of a certian lack of tone or some sterile sound, nothing of the sort, I cannot blame you for not having listened to Romys system, but theo...

Hi,[quote user="morricab"]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. [/quote] Well, the claim is no...

Dear Romy,
Thank you for the commentary and the advice with regards to the need to have a COGNITIVE ORDER OF SUCCESSION and to test with another speaker in situ first.
Given the varying degrees of how different individuals process COGNITI...

[quote user="darkmoebius"] That's because "off the shelf" amps can be easily resold for little or no loss of money if they are not to the buyer's liking. The Melquiades, on the other hand, leaves the builder with $3,000 worth of parts not easily reso...

[quote user="Tax"] Given the varying degrees of how different individuals process COGNITIVE ORDER OF SUCCESSION there will be differences in between how the plumber Vs a brain surgeon handles COGNITIVE ORDER OF SUCCESSION. I guess on some things...

[quote user="rowuk"]Amir,In live music, we have intermodulation. Two trumpets or a trumpet and oboe playing together create sum and difference tones that change depending on pitch interval for instance. For music in major keys, this intermodulati...

Hi Thorsten,
"I agree. I
have to note that even in active preamp I/We (the we are friends from
the London Live DIY Circle) tend to prefer TVC's over resistors."
Hmmm....I guess I can't really see that unless you are enjoying a
particular col...
