I’m working on this amp, plays great so far but problem I’m seen is the crossover setting when selected on the LP setting the amp makes no sound, I’ve already checked and double checked the switch and the throws are all functional on the switch, no cracked or bad solder.
The daughter board “SUB3” is missing an IC from IC2, could it be NJM2068L and also can it caused the low frequency setting to be muted(blank)?
