Can you supply a schematic for the mods? I've been thinking of where to go next and need some direction. I do not plan on doing the mods just yet, but sometime down the road it will need to be done.
The gain is a bit on the touchy side. Very little throw in the volume know gives a big increase in volume. I'll look at the foreplay mods and see what is suggested. Seems to be the same "problem" that the foreplay has. It's not really a problem, but still needs to be modified.
I know there are a lot of ideas being suggested about amps, but if we could start norrowing the choices down, that would be great. I emailed you about using something off the beaten path, and you suggested the 1619. I like the idea because the tube is cheap and not widely used in an amp. The only problem I see is that 1619s are metal-cased. Kind of a childish request, but I want to bask in the tube's glow, and this tube ain't goin' do it for me.
The 813 seems like a good choice, but the voltages scare me with my current skill set. I think that leaves the 6V6, 6L6, 2A3 and KT88. Did I leave out any? I do wnat to go PP, but beyond that I have no preference, other than I will build whatever manualblock builds. As soon as time permits, I'm going to start constructing the base for the amps, and I would like to have an idea of what's going in them.
Please, I'm not being pushy, but I'm really pumped about this endeavour. It's been a while since I've used the technical/engineering skills that I spent years in school perfecting.
