UFO25 Voltage change
12/11/24 at 08:58:53
 
Hi there, I'm in the market for a used UFO25 and would like to know if posible to switch voltage from 110V to 230V and how hard it is? I read a while ago the power transformer in UFO25B is a universal power transformer but can't see now any mention about this on product page nor in the manual. A schematic and with some guidance would help a lot. I'm in Europe. Best regards

I can't help you with rewiring your transformer, but in your situation I would consider an external step-down transformer. I've used them before with good results. My rule of thumb is the transformer ought to be rated at least 10x the power draw so for a UFO25 that would be 1000W. E.g.:

Although I'm pretty sure you can find something similar on your side of the Atlantic.

Thanks but don't want that route. I used them in the past for Japanese amplifier but not anymore.

We recommend wiring it for 240V to extend tube life.
