Voltage regulation


I have noticed that my dedicated mains power slowly fluctuates between 124 and 127 volts. Nothing seems to correlate like furnace - refrigerator turning on and off - time - day of the week etc. I'm looking for something that would keep the output a steady 120V without constricting the current. I'm not looking to break the bank but would like any and all suggestions.

The reason I'm looking for this is because I have a tube integrated where the bias goes up and down with the voltage fluctuations.

Thanks

There's some 5000VA/50Hz Sola MCR (works even better at 60Hz) on Ebay for $600. Heavy and expensive shipping. Insist on bolted/strapped to palette. These are noisy, so they have to be mounted remotely, if possible. The MCR is only 3% regulation but have much better CMNR than the CVS models. The SolaHD site has a technical/FAQ section that's educational.

Wouldn't recommend a tap-switching regulator for audio.
