Pioneer sx-780, weak channel , this for a tech .I dont have the time to go thur it.
I know the bias is good and in the power supply 3 leg black transistors should be replaced as well as several caps. This has the Darling power paks.
Was going to part it out but thought maybe someone here would want it.
cosmetically its good. Iam looking for 35.00 local pick up zip 91040.
