I have a problem with a pair of Carver 400t amplifiers.  The power supply
injects noise back into the A/C power line which interfers with the 
operation of my BSR X-10 control system.  I took one amplifier to the local
repair shop who, after 6 weeks and several calls to Carver, reports that
"this is normal and not a defect".  Ok, fine (BEWARE POTENTIAL BUYERS), but
what do I do now?

How can I filter this mess before it gets to the A/C?  Would a "computer
protector" style power line filter do the trick?  Or an isolation trans-
former?  What would one of these jobs cost for about 1kwatt of output?
Any 39 cent solutions?

HELP!

The amplifiers SOUND excellent and I don't want to have to junk them and
replace with something else.
