Nearly 200 tubes, all made in the USA. Philco, RCA, GE, Sylvania, Tung-Sol, Raytheon, Zenith, just to name a few.
No, I have not tested these. They were purchased in their entirety from an electronics dealer (The Tube Caddy, Gardena, CA) back in the 50's. In storage in the original container since then. If for any reason the tube does not meet your satisfaction, a refund will be made. You cover the return shipping.
