Question about Audio Players & Recorders
Power protection for the Stav-3990 Professional Series after 7 seconds the system will shut itself off understandable the issue inside I believe may have over heated due to a Record player siting on top while the receiver is on for long periods I never had an issue till now.
An output transistor has shorted and is drawing too much current. It's fixable, but use a matched pair of output transistors instead of just changing the bad one.

Most often it will require an output IC, but I have seen it be a bad ground or a transistor in the protect circuit.

If your receiver enters protect mode with no speakers connected, it is an indication that you will have to start troubleshooting inside.This will involve visual checking and checking with a multimeter to isolate the problem. A further issue is finding out why your JBL woofer keeps blowing fuses. It could be shorted.
