Question about Peavey ValveKing 100w All Tube 212 Combo Guitar Amplifier
You start by downloading the schematic here:
Scroll down to the link "Get Manual" and download the schematic. Note that it has several pages of parts list preceeding the schematic.
Next, put a 150 Watt incandescent bulb in series with the power cord to act as a current limiting fuse. Now replace the fuse and proceed with testing. You may find that one or more filter caps have shorted. Also pay particular attention the the BIAS power supply. You should see about -35 to -40 volts. Note that the series lamp will come on if excess current is being drawn and voltages will be low if the lamp lights. If the BIAS supply has failed, it is possible your power tubes have been damaged.
