It could be used as a power supply for a small tube amp. Most of the caps are probably not great audio caps. The resistors should be old carbon comp ones, and might be good. You'd have to check each one's value to make sure it was within it's specs to know for sure.
Thanks, Adam. I'll have my tech check it all out for me. I was mainly after the cool bakelite knobs and smooth glass pilot light jewel. All bonus if the resistors and trannie are useable.
