Build A Great VPO - Part 3: Amp Repair | Roy Creek Ranch
Just before disassembling the Thomas Transistor organ to create a VPO, I tried turning it on for one last listen. I wanted to sample a few of the basic sounds for later use building a sample set or synthesizer patches. It hadn’t been used for quite some time, though I had no reason to suspect it wouldn’t work. Within a second or two of powering the organ, there was a loud pop, followed by a very loud hum. Time to get it on the bench!
