Pioneer SX780 Sound Problems
I recently aquired a Pioneer SX-780 reciever. Powers up and all inputs work, however the left speaker channels on both A and B speakers get distorted a short time after connecting the speaker wires. If I unplug the speaker wires and reconnect them the speakers will once again work for a short period of time and then problem returns. If I switch from stereo to mono speakers work without destortion. Any suggestions on how to fix the problem will be greatly appreciated.
