Issue: Has power, but no sound.

Opened it up, reset all the connectors, cleaned the pots and started tracing. Now works. Level pot is broken, and power connector loose. contacted owner to see if we should replace or repair them. Unable to replace pots, as they are unavailable, and Crate stopped making amps in 2018, Repaired shaft and all works…until any of the knobs are turned, then all sound quits for around 30 seconds. Turning it off, then on fixed the problem, until another knob is turned.

Status: On shelf to work on a higher pripority.
