The initial power-up for this build was totally silent until a voltage check found an open on FV-1 pin 13 and an open at the stomp. After addressing those, all FV-1 pins return voltages that look plausible according to my interpretation of the schematic. When Mix is counterclockwise, Volume works and signal sounds clean, if boosted. But Mix at full clockwise kills output. How easy is it to thermally fry the FV-1?
There's probably other probing that could be done over and above a voltage check across the PCB.
