Hello Steve, for what you say, you have a problem in the power supply or speaker outputs, that's why that buzz
If you have the ability to repair it, I will send you the service manual

Hello Bernard, for your description of the fault, the Sansui AU-33 team, has problems in the output stage of speakers or in the power supply stage, you should go to a specialized technical service

Hola Bernard, por tu descripcion de la falla, el equipo Sansui AU-33, tiene problemas en la etapa de salida de parlantes o en la etapa de fuente de alimentacion, deberias concurrir a un servicio tecnico especializado

If the speaker protection is activated then this would indicate that either a dc voltage is appearing across the speakers or a short circuit on one or more speaker cables. Since you are able to get normal sound through the headphone function the former is less likely and you should check for a possible shorting speaker cable. Another possible cause for the symptoms can be dry joints on the speaker protection relays.

One thing you could look at is that thing that makes the click, it could be a relay and they do go wacky sometimes (hence why it shuts down). If you are lucky it will tell you (on the relay) everything you need to replace it.

It is possible, but nlikely that the protection circuit is bad. More common are shorted output transistors or defective driver stage transistors. This should not be a difficult repair for anyone familiar with audio amps. Unsolder/remove Q22 and Q23 and measure the voltages at each of the 3 pads per transistor and post them here.

Thanks,
Dan
