I have had an interesting problem in that my speakers will automtically
shut off at times.  I have a Sony STR-V35 (35 watt per channel), a pair
of Sony 40 watt speakers, Sony DD Turntable, and Technics cassette.

The speakers will either cut off with out warning, or you will hear
a noise link dragging a needle across a record before it will turn off.
Usually within a half a minute, they will click back on.  This also
happens when the speakers are physically off (listening to headphones).
This has also happened on a friend of mines Technics tuner.  His
father tracked it down to the speaker overload chip, of which I know
I have, but it is not the same one as his.  Are these chips bad?
How sensitive are they?

I do have lots of other electronic equipment in the room with the
stereo, such as TV, VCR, Modem, Terminal.  Is it the simple fact that
my speaker wires are acting like antennas, and picking up 
radiation and thereby triggering the overload circuit?  Is my only
course of action to go out and spend lots of money on high quality
shielded speaker cables?

This tends to be a rather annoying problem, dragging me more to
the television.  Any helps is appreciated...
