This amp plays audio for a few minutes and then stop.Is there a mute transistor in this amp?
RAIL and regulated voltage remains stable but protect led is lit when audio stops.

Is there any of that brown fixative on any components (especially in the control circuit area)? If so, remove that before you do anything else.
I remove all, I also found a leaky cap.
The amp is still behaving the same way.while the amp is in the mute state if I pull the B+ voltage the amp will produce audio befor it goes off.

You can get the diagram from this site:
Service manual, eprom result list | Elektrotanya
I've seen R11 damaged from the fixative but I don't know if it was muting related.
