FS: Amperex 4CX250F Ceramic Tube: NOS Amperex 4CX250F Ceramic output tube. Tube was mistakenly purchased to replace a 4CX250B. As we found out, the circuit for the 4CX250B is a 6 Volt filament as is the 4CX250B. We then found out that the 4CX250F uses a 26.6 Volt filament source…… so this tube is up for sale as maybe it was developed for military use with that filament voltage? $30 shipped CONUS. Not interested in trades.; Listing #1750067 - Submitted on 11/20/25 by Callsign KH6JTM - IP: c-73-242-208-180.hsd1.nm.comcast.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
