4BS8 Medium-Mu Twin Triode RF Amplifier Sylvania Electronic Vacuum Tube

This is a genuine, vintage Sylvania 4BS8 Medium-Mu Twin Triode electronic tube in it's original factory box. 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, excellent condition. Useable for replacement, antique radio, instrument restoration projects, experimentation, circuit design or to set up a private vacuum tube museum. First come first serve, as only one of this rare historical vacuum tube available!
