Braude's response, I suppose you mean 60 Hz, not 60MHz! Since 60 Hz is the nominal frequency on a power line, you don't want to get rid of it. However other electric appliances may generate harmonics of it (120, 180, etc) as well as higher frequency spikes. Your power supply should filter out the 60 Hz and its lower harmonics, but may not be good against the "really" high stuff, since that isn't NORMALLY part of the power system. With regards my comment on computer spike-protectors, they should indeed only keep out spikes and surges (if designed for both), but I wonder about their ability to handle much of a load. Except for CRT's, computers don't really draw lots of power. Jim Muller
