9AU7 Sylvania Medium-Mu Twin Triode Electronic Tube

This is an original 9AU7 Electronic Tube. A collector's special vacuum tube. This tube was developed for push-pull amplifier in ac/dc radio equipment. Also used for amplifiers, multivibrators or oscillators. 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 cathedral 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!
