Default Sansui Receiver- Noise at shutdown

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.

I have a Sansui R-7 receiver which works fine except that when the power
is
turned off there is usually a fairly loud click from the speakers. Does
not
seem to be loud enough to harm the speakers, but certainly annoying, and
not
at all what I would consider normal.

This is a low to mid power receiver which I'm guessing is from the late
80's. It is an instant-on unit with no relays. There was a place for a
capacitor accross the power switch, but none was ever installed. I
added a
.01 disc there, but that did not help. Following wires from the line
cord
thru the switch to the power transformer, I do not see any other line
conditioning or surge suppression. I can't believe it always had this
problem. Any ideas as to the cause?

Thanks,
Paul



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