7F8 RCA Radiotron Medium-Mu Twin Triode Electron Tube

This is an original RCA 7F8 Radiotron Electron Tube. A collector's special vacuum tube. This tube was developed for direct-coupled cathode-drive and push-pull direct-coupled cathode-drive RF amplifiers. It has high enough maximum frequency to allow it's use in television tuners in the VHF range. Also a good general purpose dual triode replacement. It is new, unused, boxed, and kept for all these years in mint condition. Excellent for those antique radio restoration projects or to set up a private vacuum tube museum. First come first serve, as only one of this rare historical vacuum tube available!
