This amp has audio for a slight second.There is no oscillation after the audio stops.The port in the pic got damaged while I was removing the glue,anyone know the value and the function of it?

That looks like part of the over-current protection.

What port I can put in there?
Can that be why the output section shutting down?

I don't know if that's the reason.

Can you push down on the top of the potentiometer to make the wiper make contact to see if that prevents it from shutting down?

What's the resistance between the two adjacent terminals of the potentiometer?
