8877/YU-158 Tube: This is an industrial grade 8877 tube for an Alpha 9500 and similar amps. The best (lowest grid current) tubes were pulled from the 8877 assembly line and rebranded YU-158 for the medical device market (and sold at a much higher price). This is an excellent tube tested in a 9500 and delivered full power out +. Comes with socket (which you can just pull off if you don’t need it).

For Sale: two (2) 4cx1000 tubes: From an estate. These tubes were used to power a Collins 30S-1 amplifier. I believe both to be good but have no way of testing. Selling for the widow of the deceased ham who has already sold the amplifier. They performed very well when installed but I believe they were pulled because the owner wanted "more power" and installed 4cx1500's, which were sold with the amplifier. Asking $525 shipped and insured to anywhere in the continental USA. Will accept personal check, postal money order or Paypal.; Listing #1761432 - Submitted on 03/09/26 by Callsign W8QW - IP: dyn-149.19.222.129.hrvl.mi.homeworksinternet.net; Click to Contact -- Send this Ad to a Friend

Eimac 7580W / 4CX250R: Offering this from recent estate tube lot - cosmetics indicate either NOS or very, very low hours.
The 4CX250R/7580W is the heavy-duty, ruggedized version. Like the 4CX250B, it has 6.3v filament voltage. They ( “typically” ) deliver more output in most linear amplifiers which use the 4CX250B.
My TV-3B/U tube tester doesn’t cover this one, so it’s sold As-Is / No Return.

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
