Ok, fine (BEWARE POTENTIAL BUYERS), but >what do I do now? Actually not so fine. The Carver amp may do wonderous things, but if it dumps trash into the AC line, it is DEFECTIVE. Unfortunately, I don't know of anyone who tests for this. UL is only concerned about safety, and the FCC presumably only cares about *radiated* noise, not conducted. (anyone know for sure?) The days of not having to worry about the garbage you dump into the AC line are long gone. Carver should put a filter (or whatever) in his amps to prevent this. Of course if the BSR X-10 is one of those units that puts control signals on the AC line, and expects it to be reliable, it's even more bogus...
