Just to add to the general dust cloud that the OP is removing hair over...
I had a persistent 60cps 'hmmm' that sent me on a search & destroy mission. Went through the usual 'disconnect this/eliminate that' routine on my system to no avail. Moved on to the ac circuit, unplugging or disconnecting everything, including the GFCI 's that were part of that line...
It persisted. Visions of 'Reddy Kilowatt' giving me the middle finger salute.
Spouse said "Why don't you try a different circuit?" Since I subscribe to 'the women are smarter' theory (as they've got us pretty much where they want us), I got out the extension cord...3 wire, of course.
*Poof* Gone. Beats me as to why. Only operative reason may be a noisy breaker. Since the existence of the new extension cord isn't a tragedy nor an issue I'm in no rush to buy a new breaker, BUT...
It could be that simple. Easy enough to try, can't hurt to do so.
Good luck. Spouse got thanks, big hug and kiss. ;) She likes my hobby...she likes how it all sounds as well although the complexity of 'the mains' confounds her. So the project at hand is to develop a simple 'work-around' for her to enjoy the solution as well. *S* Marital bliss requires maintenance...;)
