A compactron used in television sets to supply power to the anode of the picture tube. This tube is very rare, and very special, because it implements an indirectly heated cathode, not connected to the filament. No data is found on this tube, except for the filament power (which is 3.6 volts, 0.225 amps) and the base (which is the 12GQ type).
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.
Reduction drives are used in engines of all kinds to increase the amount of torque per revolution of a shaft: the gearbox of any car is a ubiquitous example of a reduction drive. Common household uses are washing machines, food blenders and window-winders.
The power produced by an engine increases with the engine's RPM to a maximum, then falls away. The point of maximum power is somewhat lower than the absolute maximum engine speed to which it is limited, the "redline". A car's speed is limited by the power required to drive it against air resistance, which increases with speed.
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 ...
It belongs to a large family of dual-triode vacuum tubes which share the same pinout (RETMA 9A). 12AU7 is also known in Europe under its Mullard–Philips tube designation ECC82 . [ 1 ] There are many equivalent tubes with different names, some identical, some designed for ruggedness, long life, or other characteristics; examples are the US ...
It can also be on the circumference of a dowel, a bolt, an axle or on the outside or inside of a tube or pipe etc. This canal may receive a circlip, an o-ring, or a gasket. A depression on the entire circumference of a cast or machined wheel, a pulley or sheave. This depression may receive a cable, a rope or a belt.
A modern Chinese-made 845 tube. The 845 power triode is a radio transmitting vacuum tube which can also be used as an audio amplifier and modulation tube. Typically, the plate is machined from solid graphite in order to accommodate high power dissipation (up to 100 watts) and voltage. Some current production 845 tubes have metal plates.
