Model 90 Stuck At One Volume Level
#5

Yeah morzh I drilled that rivet out during the resto because it looked a little corroded. I reused the ground strap, it's good but I replaced the rivet with a small screw, lockwasher and nut. My lead resistance is .1 ohms and the volume ground reads .1 ohms.

It's late here so I enlarged two more copies of the schematic to 11X17 and in the morning I'm gonna go through the whole circuit and highlight each section as I go. This will be the third time. If I'm missing something I must be blind. I can ground the grid on the Det. Amp. and I still have volume. So I still have an audio signal going into the 1st AF from somewhere.

Appreciate the help from all of you! Let you know what I do or don't find.
