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

I don't hear a difference but am more afraid of damaging my equipment.

Chuck It raises the output voltage by 3V. That pushes the output to 130V. Other than that the Topaz Isolates only. No regulation.

Hey Everyone Thanks for the responses. Any recommendations for a sub 1k budget limit (new or used).

10 volt swing per day WOW. As far as linear power supplies they are generally designed to work with +/- 10% of the standard 120v. So for me I would think 132v would be my upper limit. At any rate I have been trying to keep my bias down. I've lost 4 tubes in 4 months. All in different locations in my integrated. 2 tubes blew when no music was playing.

Thanks Irish - Yes both the distributor and manufacturer both are aware of that problem. They have been very good about tube replacement too. I think I'm on the last step of things to look for and try before sending it in for repair.
