A neighbor has a stereo receiver from the 8-track days. He listens on it to his favorite station every day. Yesterday he got loud white noise on both channels, as if he were tuning between stations with the volume turned up.
Turning down the volume control and changing sources don't affect it, so it must be in the power amp. What failure could cause white noise in both channels of a stereo amplifier?
Choreboy: You are probably correct in your assumption..... a failure in the power amp circuitry...... output devices? coupling electrolytics? driver transistors? faulty solder connections?

amp
noise
volume
so
multiple failures (stuck on FM tuner and volume control failure)
listing make and model might be helpful.
if its a cheapie from sears it might be time to replace it with a cheapie from wallmart
The owner was mistaken. The noise was on one channel. With a scope and a multimeter, I determined that the problem is within the amplifier IC. It's time for him to buy another garage-sale receiver.
