This listing is for a lot of five (5) new old stock (NOS) RCA JRC 12AT7WA Electron Tubes. These are high-quality vacuum tubes manufactured by Radio Corp of America, as indicated on the original packaging. Each tube is marked JRC 12AT7WA and the boxes bear the FSN-5960-262-0167 designation, indicating military or industrial grade. The packaging date is PKG 1-63, suggesting these are vintage components. They are similar to the CV4024 tube. Ideal for vintage audio equipment, guitar amplifiers, or electronic projects requiring reliable dual triode tubes. Tubes are in original boxes, condition as shown in images.


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.
