Sansui Receiver- Noise at shutdown

Probably not much you can do except switch off the speakers before you turn the unit off.

Mark Z.

The easiest way to fix this, is to switch off the speakers before turning the set on. If you are innovative enough, you an design and build a relay circuit using a turn on time delay circuit. The speaker path can be through the relay contacts. This way, when you turn the set on, the relay can have a 2 or 3 second delay.

This is a low to mid power receiver which I'm guessing is from the late

Thanks, Paul

Ahhhh! Hrrrmm! the OP has the prob with shutdown so some mod to the cct would be required I imagine.

Both replies indicate that this is normal operation, not a defect. I find that hard to believe. If bought new and it had this problem, I think that most people would take it back for a refund.

Anyway, I thank those who took the time to reply.

(BTW Jerry, since it happens at shutdown, not startup, I would need to add an anticipation circuit, not a delay circuit ;-)

FWIW, I have a mid 80's Realistic reciever. I was looking through the service manual and noticed that the amplifier IC has a delay feature built into the chip itself. Perhaps it is possible that this type of circuit could go bad, but the amplifer would keep operating? Just a thought.
