7F8 Medium-Mu Twin Triode RCA Radiotron Electron Tube

This is a rare, original RCA 7F8 Radiotron Medium-Mu Twin Triode electron 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 and also it is a good general purpose dual triode replacement. It is new, unused, boxed, excellent condition. Excellent for antique radio restoration, projects, guitar amplifiers or to set up a private vacuum tube museum. First come first serve, as only one of this historical vacuum tube available!
