THis is more likely pickup of externam magnetic or electrical fields, or pickup of noise from the AC power line - light dimmers, TVs, CRTs and switching power supplies are a real factor here).
I was up at my uncle's a few weeks ago and he asked me 'what's that noise in my amps?'. He has a pair of the first Eiclones on his work bench in the garage, and just above the bench is a flourescent work light. Turned that off and the Ikes were silent. I think he just re-routed the power hook-ups. That said, my work lights have never caused this phenomenon. Probably due to the ballast type?
