Replacing a Power Supply Resistor
Peavey Classic-30, Front Peavey Classic-30, Rear

This Peavey Classic-30 guitar amplifier was producing no sound when it came into the shop.

 
 

Troubleshooting discovered an open power resistor, R58, which conducts current to the EL84 screen grids and to all the preamp tubes.
