  2. Beam tetrode - Wikipedia

    en.wikipedia.org/wiki/Beam_tetrode

    The beam tetrode produces greater output power than a triode or pentode with the same anode supply voltage. [ 3] The first beam tetrode marketed was the Marconi N40, introduced in 1935. [ 4][ 5] Beam tetrodes manufactured and used in the 21st century include the 4CX250B, KT66 and variants of the 6L6.

    en.wikipedia.org/wiki/Vacuum-tube_computer

    A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. While the history of mechanical aids to computation goes back centuries, if not millennia, the history of vacuum tube computers is confined to the middle of the 20th century. Lee De Forest invented the triode in 1906.

  8. Compactron - Wikipedia

    en.wikipedia.org/wiki/Compactron

    History. The Compactron was a trade name applied to multi-electrode structure tubes specifically constructed on a 12-pin Duodecar base. This vacuum tube family was introduced in 1961 by General Electric in Owensboro, Kentucky [ 1] to compete with transistorized electronics during the solid state transition. [ 2]

  9. KT88 - Wikipedia

    en.wikipedia.org/wiki/KT88

    The KT88 was introduced by GEC in 1956 as a larger variant of the KT66. It was manufactured in the U.K. by the MOV ( Marconi-Osram Valve) subsidiary of G.E.C, also labelled as IEC/Mullard, and, in the U.S., Genalex Gold Lion. [ 2] Four KT88s installed and powered. As of 2022, KT88 valves are produced by New Sensor Corporation ( Genalex Gold ...
