1. The 2 "Heater" Caps (.02 uf ceramic): I've read ceramics are noisy, is there any value in using vintage pio's if I have them?
2. On the VTA70v11 board, what are the "upgraded" values for C13,C14,C15,C16,C17,C18? from the standard 88uf on board?
3. C9 and C10 (cathode resister bypass capacitors?) are omitted on the VTA70v11 board. Please explain.
Thanks in advance, I'm sure I'll have more questions as I go along.
PS-Do you have any info on the Sound Valves VTP-101 preamp? I've been looking for a schematic and can't find anything at all. I read an older post that mentioned how loud the VTP-100 was at it's lowest setting. My solution to that problem was to substitute a 5751 tube at V4, the effect was fantastic (I'll never go back to 12ax7 at V4). Much more dynamic, clearer, forward, subtle, everything improved. Thanks again.
