Peavey 5150 Troubleshooting and Repair + Bias Mod Tips and Play-through

Repair Blog 002
In this episode I go through a Peavey 5150 that had a few problems. The ribbon cable that carries the heater voltage supply from the main board to the output tube board has burnt the traces on the PCB and must be replaced. To make the repair even more fun I had to go through many different troubleshooting methods to find some hidden cold solder joints left by a previous "tech".
An adjustable bias mod had been installed and I had changed one of the values of parts in order to get the bias into the correct range. I tried my best to detail those steps in this video for those interested in carrying out this modification.
Fast forward to the end to hear the 5150 in action!
