Voltage Step Down/ Regulator

[Dylanthecat]

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

Did you find something to sort your issues? I've just moved and have hot mains as well, and a couple of my amps have a buzzing transformer and even a hum on the speakers when plugged in.

Confirmed it's not a DC offset in my case, and an online UPS resolves it, so my latest theory is that it's the voltage.

Martin I had the exact same problem. I bought a balanced mains unit that stepped the voltage down slightly to about 220v.

That was about 3 years ago and my valve amp has operated OK at this voltage since then.
