Question about Audio Players & Recorders
Hello Big Red,
I think it's the speaker protection circuit coming on and off on the second channel. I swapped speaker channels after the first channel gave up. Before it died it started to take a long time for it to click in.
Do a websearch for a competent repair shop in your region or ask the stereo folks where you got the amp.
It WILL need surgery.

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be with your output drivers. Please check for short on the outputs fitted for both the channels. Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise which can be a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board. Maybe the protect circuit by itself is shutting off due to a faulty bias or there is a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the amplifier comes out of the protect mode then check for short on the speakers.Check manual to see if there is a reset or the processor can be a suspect.
