Hi Mickey.
Went through the cap operation. Started with a 3.3uF, then went to the 2.2uF. I had one more, 1uF. I stopped at the 2.2. Man she roars now. I turned the mid pot to zero and there was my sound. It tightened up in an incredible way. I may immagine it, but it feels like itīs better sounding over the whole register. Wish I could post a demo but the mic in my mac wouldnīt cope. You have to crank it a bit, like 10 oīclock. Seems little but trust me, these 100w are loud. Thatīs my volume with the band. The original value was 250uF/25V.
I looked it up on where to measure the cathode voltage and concluded that it was on pin 3. I had +90mv. I put the red probe on pin 3 and black to ground, chassis. That has to be wrong, right?
Many thanks dude
