Using a shore power isolation transformer at home?

Can a shore 1:1 power isolation transformer, rated 120V/60Hz and sufficiently powerful, be used in order to make a (dedicated) AC line at home cleaner (reducing neighbor's noises)?

Is there anything special I shall take into account (as opposed to installing a "home-oriented" isolation transformer)?

If I do not want the output to be balanced (would be pointless or even harmful, as I have a servo-operated variac between the receptacle and my tube amp), what is the recommended way to earth the isolation transformer?

Thanks!

I don't understand how an isolation transformer would help with voltage fluctuations.

Face,

Isolation transformer is to address the input transformer vibration that is caused by something in the AC. Fluctuations are to be addressed by that servo-regulated variac. Sorry, I brought another topic under the same thread.

ultimately, the amplifier needs sufficient current to do its job and the ac needs to free of noise. if voltage gets to low, some amps will have a problem. within a range, the actual voltage probably doesn't matter.

is it noise pollution or low or high voltage that causes changes in frequency response during the summer months ?

Mrtennis,

It is hard to know remotely, but wrong volage is probably the easiest thing to detect, just measure it. If it is indeed too low, might be possible to demand your power company to fix it.

Do not forget that you will pay for energizing the coils of the transformer and it can cost more when your equipment is off than on. I tried this and it was not cost effective IMO, 4 amp input draw at static with no output load. I put it on the back burner for now till I can figure out how to put it on a starter without tripping the breaker 20% of the time. Fuses may work I just have not the time to try it yet.
