I am new to this forum and I want to thank anyone in advance who can
help me with my problem.
My friend's stereo amplifier has not worked for a while and I just
surprised her by replacing her amp ( Onkyo ) with a Yamaha A 700.
After connecting everything the stereo seemed to work fine but then
the sound suddenly cut off ( with an audible click) the came back on
a few seconds latter. This would happen everytime I turned up the
volume or changed the balance or switched from stereo to mono.
Apparently this is what happened with her old amp!! The amp seems to
cut off in response to some increased load. She live in an old row
home that has been partially rewired. The outlet is fused to a 20
amp fuse, and the fuse does not blow.The speaker wire runs through
the walls and connected to terminals on a wall plate. A TV pluged
into the same outlet works fine. (not running TV at the same time).
there is no hum or distortion and the amp does not feel hot. At low
vol it plays without cutting out. What could be the problem ?

Shorted speaker wires. If the wall plate is metal, that's where I'd
check first. Easy test. Obtain some speaker wire and hook the
speakers directly up to the amplifier and see if the problem remains.
If it does, then the speakers are faulty. Rare but it occasionally
happens. Chuck

Classic speaker wire problem.
