Save on Unpopular and Low Grade tubes!

Unpopular Vacuum 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.

Low Grade Vacuum Tubes

Some tubes fail testing because they have a weak output, are leaky, or have a minor defect such as a missing cap. These tubes can still be usable to experimenters, as backup tubes, or in an undemanding service may still operate as well as a new tube. We offer them here at a reduced price.
