my PC and speakers, etc are about 3 feet away on a separate circuit 
from the SB220 and I often have to unplug the speakers because I can 
hear myself thru them in spite of my Heil headset.

I have considered getting a GI steel trashcan and lid and suspending 
the amp inside it - I guess that if I had an ALS500 like remote head 
for it, I would have already tried it.

any less radical suggestions?  I assume we do want a grounded faraday 
cage surrounding the amp, don't we??? <G>
