I’ve searched hi and low for schematics, but no luck. Does anyone know what transistor Q4 on the daughterboards is? I’ve tracked my problem down to that transistor (I hope) and a burnt 10ohm resistor on the same daughter board. All other components test OK including the other transistors. (At least with a simple DMM diode teat.)
Swapping with a daughter board from another channel solves the problem. So if I can just replace that transistor, all should be well.
