    en.wikipedia.org/wiki/Vacuum_tube

    A vacuum tube, electron tube, [ 1][ 2][ 3] valve (British usage), or tube (North America) [ 4] is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a ...

    12AU7. The 12AU7 and its variants are miniature nine-pin (B9A base) medium-gain dual- triode vacuum tubes. It belongs to a large family of dual-triode vacuum tubes which share the same pinout ( RETMA 9A). 12AU7 is also known in Europe under its Mullard–Philips tube designation ECC82. [1] There are many equivalent tubes with different names ...

    The 6SN7 was one of the most important components of the first programmable electronic digital computer, the ENIAC, which contained several thousand of the tubes. The SAGE computer systems used hundreds of 5692s as flip-flops . With the advent of television, the 6SN7 was well suited for use as a vertical-deflection amplifier.
