Save on unpopular tubes!

We have many tubes that are in new and like new condition that are not popular. Because of the lack of popularity, they are not worth the effort to test them. The tubes are just as they came in from our suppliers. If you need an unusal tube, or just want to experiment with tubes without paying a lot of money, here is a chance to get some at a very low cost. The unpopular Bargain Bin tubes have NOT been tested.

Don't see what you need? Contact us. We have many more tubes that are not yet listed. We also have new and good used tubes in most other numbers including preoctal, globe/balloon, octal, loctal, miniature, subminiature, metal, power, transmitter tubes and many more.
