veatch Posted June 24, 2011 Posted June 24, 2011 OK all you amp builders... Are these useful for noise suppression in audio amps, or only computer and medical equipment? I'm sure clean power has to be a good thing, right? Just curious as i see these a lot in the equipment i work with, but have never seen an amp with one...

Thundernotes Posted June 24, 2011 Posted June 24, 2011 I believe they're primarily for keeping the noise produced by switch-mode power supplies (RF noise) from feeding out of equipment back to the line, and not so much for keeping noise out. The noise they're designed to suppress wouldn't be audible anyway. In most guitar amps, I think they'd be overkill.
triodecr Posted June 24, 2011 Posted June 24, 2011 I put a varistor across the hot and neutral to suppress spikes. I haven't done any listening tests to see what effect it has on noise.http://www.alliedelec.com/search/productde...spx?SKU=8460244
