6P1P tube manufactured by Svetlana, USSR (winged "C" logo), 1971 A comparison of Svetlana 6P1P (left), 6P1P-EV and Beijing Electron Tube Factory 6P1 (right) The 6P1P (Russian: 6П1П) is a Soviet-made miniature 9-pin beam tetrode vacuum tube with ratings similar to the 6AQ5, EL90 and the 6V6. Because of a different pinout (a 9-pin base versus 7 ...
This is a list of vacuum tubes or thermionic valves, and low-pressure gas-filled tubes, or discharge tubes. Before the advent of semiconductor devices, thousands of tube types were used in consumer electronics. Many industrial, military or otherwise professional tubes were also produced.
Later tubes include the 3CX5000A7 power triode and the 4X150D tetrode. The new company thrived during World War II by selling tubes to the U.S. military for use in radar equipment. [ 2 ] Charles Litton Sr. originated glass lathe techniques which made mass production of reliable high quality power tubes possible, and resulted in the award of ...
Later thermionic vacuum tubes, mostly miniature style, some with top cap connections for higher voltages. A vacuum tube, electron tube, [1] [2] [3] thermionic 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.
Electron tube may refer to: Vacuum tube, a device that controls electric current between electrodes; Gas-filled tube, an arrangement of electrodes in a gas
The TWT is an elongated vacuum tube with an electron gun (a heated cathode that emits electrons) at one end. A voltage applied across the cathode and anode accelerates the electrons towards the far end of the tube, and an external magnetic field around the tube focuses the electrons into a beam. At the other end of the tube the electrons strike ...
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. The original AT&T-based ...
The heater has a 6.3 volt rating, which it shares with many other common thermionic valves/electron tubes, and it draws about 150 mA. The maximum anode voltage is 250 V, with an anode current of 420 microamperes and anode load 250 kilohm, and the maximum anode current is 4.5 mA at a voltage of 180 V with an anode load of 20 kilohm.
