Question about Sony STR-DE597 Receiver
The amplifier stage, which consist of power transistors, is experiencing an overload. Possibly due to the transistors breaking down or the DC threshold level is too high. The latter can be adjust when the input to the transistor is at quiescent or when no input is entering the transistors. I recommend having a professional make the adjustment.
