Hi All,

I am in need of a voltage step down/ regulator to protect my valve amps. I need to ensure that the supply is kept to 230V (it currently sits during the day at 244-246V but does measure as high as 250V on a regular basis).

Any ideas of where I can procure such devices would be greatly appreciated. I have seen one online with a fanciful audiophile description and extensive performance claim list along with a price tag to match. I am looking for something a little more humble that does not introduce significant levels of unwanted noise into the system.

There must be something aimed at sensitive general electronic equipment.

Thank you in advance of any suggestions provided.

All the best, Martin
