Hi, I have a Hotrod Deluxe that has a bad farty distortion and it seems to be coming from the power amp (this is one of 2 HRD that are used at the Shasta Blues Society) The other amp sounds great! I tried plugging into the power amp in and it seems to be where the problem is as I have done this with both amps. And they have both been retubed and recapped, all voltages seem fine or are very close to the schematic. it sounds like its starving voltage, the sound you would get as if you hit a note and turn off the amp, just right as the voltage starts to drop, I swapped out PI .1uf caps and .022uf PI input cap, still that bad distortion.. Has anyone come across this? I even tried a different opamp in the effects loop. Resistor values seem to be in tolerance as well.... Any takers? Please? I thought it might be the output tranny as I get a slight different resistance reading from the brown to red and blue to red (86 and 111) Can that be a problem or is that tolerable?
thanks!
