What are some symptoms of this receiver not producing any sound. Has power just no sound.
Pre-amp out-amp input jumpers not installed; protection relay engaged because there is a problem in the power amplifier; tape monitor switches in wrong position; blown fuses; power supply problem; speaker switch in wrong position; bad speakers; bad cables; poor connections in audio amp.
Thanks. The protection relay might be it, I went thru a lot of this list to eliminate most. A relay might be it. Has anybody worked on these before and if so where would this relay be?
If the relay is not coming on (and letting the audio signal pass to the speakers), then you have a problem in the amplifier. When the relay comes on you will hear a slight click.
How easy is it to check/replace amp of it is bad
Just about any defect in the power amp would cause the protection relay to stay off; the circuit is designed to detect any DC on the outputs, which indicates a component failure. You would need the services of a technician to troubleshoot an amplifier. It's possible you also have a power supply failure.
