Hey, i have a Pioneer SA-510 amplifier which one day the left channel stoped working. Does anybody have any idea on which may be the cause, or if you have any info i would apreciate it!
You are lucky that one channel still works so you can use it as a sample for voltages. Then simply compare its good voltages with the same locations on the dead channel.
Its transistor stages are probably direct-coupled, so that a single fault will affect many voltages. Start with the output transistors. If the amp's output was shorted or was driving too many speakers in parallel then the output transistors or maybe a fuse is gone. :lol:
