It's not really an old neighborhood, it is somewhat rural however. It's a 200 amp service running off a fairly new transformer.
My UPS is telling me there is a large voltage fluctuation, I haven't tested it with my MM yet (I will in the morning).
I will also test the Amp in another building on the property tomorrow (seperate service/brand new transformer, 400 amps).
However I believe it is just an issue of the Amp being over sensitive, in my old house (on the other side of the country) the Amp would also clip occasionaly when a large load was turned on (Table Saw).
The reason I asked about a capacitor is that I know they use them with large amp's in car stereos.
Anyways, I will do more thorough testing tomorrow.
