The thumping was reduced after the increase to 100uf. The resistor had already been changed.
I see where R155 (69k) near the Intensity pot is also 1% and that has been changed to a 68k and a 1k in series using carbon film 2% from the prior mechanic. I just checked all of the 1% resistors remaining and they are all dead on with the exception of the 69k and 392k. Is not having a 1% resistor in a position that critical?
Just reassembled the amp and now there is a noise in the circuit.
Time to call it quits for today. Thanks!
