6SN7
The 6SN7 tube is a medium-mu twin triode in an octal based package, usually glass, although some metal envelope types were made. In normal use it operates as a class A amplifier. It was widely used in the early days of television as the vertical amplifier, and it's use was so common in most TV chassis designs that vintage 6SN7 tubes are still fairly easy to find today. Audio designers soon found it made a great audio preamp with it's large plates, ample power reserve, and low microphonic octal package. The GTA and GTB types, having been fine tuned for demands in television chassis vertical sweep circuits, can handle up to 7 watts maximum plate power!
