This listing is for a Raytheon JAN-CRP-5842 Electron Tube, also known as a Vacuum Tube. These are new old stock (NOS) items, similar to CV 3789, as indicated on the original packaging. The tubes were packaged in December 1963. They are manufactured by Raytheon Company. Ideal for collectors, vintage electronics enthusiasts, or repair projects requiring this specific military-grade electron tube.

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.
