This listing is for a lot of vintage CBS Electronics JHY-0A2WA / 0A2WA electron tubes, also similar to CV-4020. These are New Old Stock (NOS) in their original boxes (NIB), manufactured by CBS Electronics in the USA. The tubes are dated packaged 5/60 (May 1960), making them true vintage components perfect for restoring classic audio equipment, radios, or other vintage electronics requiring an 0A2WA voltage regulator tube. THREE tubes are included in this lot. Please refer to the images for condition and details. These tubes are untested.

This tube is part of a rare find — a collection of NOS (New Old Stock) military surplus vacuum tubes that were originally procured for use at the Air Force base at Cape Cod. These tubes were never put into service and have been stored in climate-controlled conditions in their original boxes since manufacture. Recently acquired from a private Connecticut estate, this is as close to true NOS military spec as it gets. Tubes are in original packaging and have never been installed or tested. Sold as-is, untested, but stored properly for decades with no signs of damage. Combined shipping available — buy multiple listings and only pay shipping once.
