small difference in the 2 amps.... the Frankenstein uses a "Hail Mary" type of biasing on the 300B as far as I can tell. The sound is very dependent on the plate voltage of the 6EM7. Good luck getting the 2 to sound the same.
Bypass capacitor position?
Hi all. I've had a pair of Coincident Frankensteins for a number of years and just opened them up to put in new capacitors. In doing so, I discovered that the previous owner had installed bypass caps on the power supply capacitor bank. Those bypass caps are, however, in different positions on the two monoblocks. Obviously they're both within the same capacitor bank, just linking different parts of the chain, so perhaps that isn't an issue.
Sometimes I think I can hear a small difference in the two amps, but if it's there it's really subtle and I may be creating a self-fulfilling prophecy.
Can anyone provide input on if this fact will change their operation/sound? I'm trying to figure out whether to cut one of them out and move it, and if so, which is the appropriate position...
