Offered here is a stellar matched quad lot of 4 vintage, Military Grade JAN-3B24 high-voltage rectifier valves, beautifully preserved in their original military boxes. Made in the USA by Raytheon, these robust tubes feature high-grade Grey Round Plates, a Bottom Leaf Getter configuration, a rugged Black Base, and a Top Cap terminal.

This select batch has been meticulously evaluated on a laboratory-grade AVO Type 160 tube analyzer. As highlighted in edited-image.jpg, the precise vintage date/production codes are printed clearly on each base. Following the template standard verified in image_09bd7d.png, the results below present the measured anode emission current relative to the 100% target factory design specification (Nominal = 30.0 mA).
