In military applications, a high-power vacuum tube can generate a 10–100 megawatt signal that can burn out an unprotected receiver's frontend. Such devices are considered non-nuclear electromagnetic weapons; they were introduced in the late 1990s by both the U.S. and Russia. See more A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied. See more The 19th century saw increasing research with evacuated tubes, such as the Geissler and Crookes tubes. The many scientists and inventors who experimented with such tubes include Thomas Edison, Eugen Goldstein, Nikola Tesla, and Johann Wilhelm Hittorf. … See more Most modern tubes have glass envelopes, but metal, fused quartz (silica) and ceramic have also been used. A first version of the 6L6 used a metal envelope sealed with glass … See more The generic name "[thermionic] valve" used in the UK derives from the unidirectional current flow allowed by the earliest device, the thermionic diode emitting electrons from a heated filament, by analogy with a non-return valve in a water pipe.

WebApr 21, 2024 · Power Supply. Vacuum tubes generally require separate low-voltage (6V to 12V) and high-voltage (100V to 250V) power supplies. The low-voltage supply is for the tube’s heater, which literally heats the tube to a temperature at which electrons will flow. High voltage is applied to the plate or anode, which attracts that flow of electrons. These ... reactionary dictionaryWeb(Image courtesy of AT&T.)
