I have a closely matched quad (4 tubes) of military/ATC (Air Traffic Control) JG12AT7WA 6201 tubes for sale. These are GUARANTEED BRAND NEW tubes with the original boxes. 3 of the tubes have a date code of 5-30 (30th wk of 1955) and the other has a code of 5-22 (22nd wk of 1955). These tubes are marked with yellow paint which is indicative of "low-noise" which would be desired for air traffic control. The boxes are marked with yellow paint as well. All 4 were purchased MANY YEARS AGO at the government auction of an air traffic control sub-station in Central Missouri. These feature shiny short black plates, D-getters, and triple-mica construction. $325 +$12 shipping. Thanks for reading my ad.
