Details:

This is a vintage tube tester electron test set. I did not even plug it in. There is no manual. It may work it not.

It is untested. The face plate and dials don't seem like they have a lot of wear. The case has dents and dings flaking paint. I would not know how to use it or test regardless.

The inside looks pretty good.
