Up for sale here is this huge. Power transformer, dated 1957 and Made in USA. This was removed from a vintage Raytheon Microtherm heat radiation machine. I tested this, and with a 120v input (terminals 1/2) I tested the secondaries at 1460v (#4/5), 2910v (#4/6), 1460v (#5/6), and 360v (#3/4). Transformers usually test a little high when they’re not loaded, but these are still crazy high voltages. This is a massive transformer, so it should be good for plenty of current. This is used with light to moderate overall wear, and looks really good. It is guaranteed to work for you. This has some great specs and would be awesome for building something crazy. Please see my pictures for details and dimensions. If you have any questions, please ask. I have more transformers and other vintage electronics listed–feel free to take a look!

Didn’t plug it in but fuse looks good.
