    YD1336 – 1.8 kW, Air-cooled, UHF power triode. YD1342 – 30 MHz, 530 kW, Water-cooled RF power triode. YD1352S (8867, DX334) – 5 MHz, 2 kW, Water-cooled Neotron, a gridless field-effect tube where a magnetically focused electron beam is modulated by varying the voltage of a gate electrode surrounding it.

  3. Vacuum-tube computer - Wikipedia

    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.

  4. Vacuum tube - Wikipedia

    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 ...

  5. Western Electric (tube manufacturer) - Wikipedia

    en.wikipedia.org/wiki/Western_Electric_(tube...

    Western Electric Export Corporation (or simply Western Electric) is a manufacturer of vacuum tubes and high end audio gear. Based in Rossville, Georgia, the company builds an ultra-premium version of the 300B electron tube. It traces its roots to 1872 with the Bell Telephone Company and the original Western Electric.

  6. Vacuum tube battery - Wikipedia

    en.wikipedia.org/wiki/Vacuum_tube_battery

    Vacuum tube battery. A generic triode vacuum tube circuit showing "A", "B" and "C" batteries. In the early days of electronics, devices that used vacuum tubes (called valves in British contexts), such as radios, were powered by batteries. Each battery had a different designation depending on which tube element it was associated with.

    en.wikipedia.org/wiki/12AX7

    12AX7 (also known as ECC83 [1]) is a miniature dual-triode vacuum tube with high voltage gain.Developed around 1946 by RCA engineers [2] in Camden, New Jersey, under developmental number A-4522, it was released for public sale under the 12AX7 identifier on September 15, 1947.

  8. Crookes tube - Wikipedia

    en.wikipedia.org/wiki/Crookes_tube

    The anode is the electrode at the bottom. A Crookes tube (also Crookes–Hittorf tube) [1] is an early experimental electrical discharge tube, with partial vacuum, invented by English physicist William Crookes [2] and others around 1869–1875, [3] in which cathode rays, streams of electrons, were discovered. [4]

  9. Tetrode - Wikipedia

    en.wikipedia.org/wiki/Tetrode

    Tetrode. A tetrode is a vacuum tube (called valve in British English) having four active electrodes. The four electrodes in order from the centre are: a thermionic cathode, first and second grids, and a plate (called anode in British English). There are several varieties of tetrodes, the most common being the screen-grid tube and the beam tetrode.
