yes, I had a feed back problem at first. To correct it i just reversed
the hot\neutral line connections feeding the system, this took care of
most of it. I now use a small, cheap in line filter (like the ones
installed into pc power input plugs) to eliminate all feedback's.
digikey sells these very cheap.
