Hi guys
Im newby here so be gentle with me. I have a 1980 sony falcon power amp (tan 15 f ) , both channels work with very good sound quality to my ears , after around 5-10 minuits there are low volume popping to right channel. I have cct. layout etc and have uploaded it , I did think should I replace all elect.caps on boards first. I have a good multimeter (fluke auto) to hand and a signal gen also.
Any help would be great . Manual is attached to this thread,
