I wonder if there is a bad connection, or cracked solder joint.
If you pull the chassis out and use a sharpie or some other non-conductive item to flex the PCB a little bit you could test that theory.
I suppose it could also be a wonky coupling cap... but I typically don't see the caps in amps from that era of Ampeg fail like that.
