Many tubes transmitting and Miniatures: I am selling loads of vacuum tubes, both transmitting and miniatures and in between. Some new in box and others not. None have been tested. Examine the photos to see what you are buying. No picking or choosing. Buyer takes all! The tubes are some many ham estates that my late husband (WK9Q) bought over the years. $1,000.00 takes all. Local pick only. More photos available upon request.; Listing #1762684 - Submitted on 03/21/26 by Callsign VIRGINIALAWTON414-418-0116 - IP: syn-174-097-148-036.res.spectrum.com; Click to Contact -- Click Here to View Picture -- 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.
