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.
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.
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.
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 ...
The ATS-25 is a military version with ceramic base. The Г-807 (G-807) is a Soviet/Russian version. The 6П7С (6P7S) is similar to Г-807, but with an 8-pin octal base. The 807 also found some use as a horizontal output tube in early TV receivers, particularly those manufactured by DuMont.
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]
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 ...
Rogers Vacuum Tube Company (formally named Radio Manufacturing Corporation Limited) was founded as the Standard Radio Manufacturing Corporation in 1925 by Edward Rogers (1900–1939) to sell Rogers "Batteryless" radios using vacuum tube technology. [1] [2] It was later renamed Rogers Majestic Corporation Limited when Rogers merged his company ...
