Perfect for your custom built amateur radio or tube amplifier. Are know as top of the line Transformers. This has got to be one of the nicest power transformers I’ve ever ce across. These older units by them have become hard to find. Especially this many watts. It’s possible this Transformers has never been used judging from the way the original power cord is rolled. It has some light rust on the bottom from just from sitting around. Adjustable Output from 205 to 240.
