Lot of 4 JAN 813 Transmitting Vacuum Tub: Lot of four vintage 813 transmitting vacuum tubes from storage. Includes military JAN tubes from RCA and Westinghouse. These were used in ham radio transmitters and RF amplifiers.
All tubes are intact with no cracks and the getters appear good. Filaments were checked with a meter and all show continuity.
Tubes have been stored for many years and are sold as untested beyond filament check.
Great for ham radio transmitter projects, restorations, or collectors.
813 tubes were commonly used in high-power RF transmitters and are getting harder to find.
See photos for condition. $400.00; Listing #1761199 - Submitted on 03/07/26 by Callsign NONE, Web Site: https://I don’t have one - IP: 57.sub-97-191-196.myvzw.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
