I find bad capacitors with an ESR meter and replace the bad ones and any similar ones. At this age you might just re-cap the whole board. Also check for cracked solder joints wherever cable harnesses connect to it. I just braid off the old solder and re-do all the joints if any are cracked. -- Ryan C.
