    Default Voltage Step Down/ Regulator

    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

    Hi Martin,
    I've supplied 'bucking transformers' to a few folk for just this use. In the main it's been to reduce 245 or so volts to 220 for Chinese amps, but I've equally made units to take nearly 250v to 230v. Cost is around 100 odd and they operate without producing heat or any other bad side product.

    A mains regenerator will output a very steady 230v give or take the odd 0.1v, I used a ag1500 - Power Inspired, but took it back out as I couldn't hear a difference, but it will do what you want. They seem to go for 250-300 used. They are a bit on the big side though.

    Thanks Mike, thank you for the response. I am in Hove and it can top out near the 'declared voltage' limit (253V as I understand) in this particular part of town. All the best, Martin
