This listing is for a matched pair of Sylvania 6AN8A vacuum tubes. These are New Old Stock (NOS) and come in their original government contract boxes, clearly marked with a 'Date Packed 2-66'. Manufactured by Sylvania in the USA, these electron tubes are ideal for restoring vintage audio and video equipment, tube amplifiers, or for collectors. Each tube is marked 'MADE IN USA' and comes in its individual box. These tubes are from contract number DSA-9-25237.

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.
