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.
The Fetron was a range of solid-state, plug-compatible replacements for vacuum tubes (valves).. Fetrons were manufactured by Teledyne Semiconductor from 1967; primarily as a low-maintenance and low-power swap-in to replace vacuum tubes, which were becoming increasingly obsolete and difficult to source with the widespread use of solid-state electronics.
When tube equipment was common, retailers such as drug stores had vacuum tube testers, and sold replacement tubes. Some Nixie tubes were also designed to use sockets. Throughout the tube era, as technology developed, sometimes differently in different parts of the world, many tube bases and sockets came into use.
ST – Shouldered tube; GT – Glass tube; MT – Miniature tube, such as Noval B9A or Miniature 7-pin B7G; FL – Subminiature all-glass elliptical body and flat bases with long, inline "flying leads" (wire-ends) that are soldered into the circuit
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-pin base) than an 6AQ5/EL90, it cannot be used as a plug-in replacement for these types; however, it will work in the same circuit with component values ...
EA53 – Co-axial instrumentation rectifier diode up to 1 GHz, Rocket-type disk-seal tube; EA76 – Diode, 5-pin all-glass wire-ended; EA111 – Diode for time bases, Y8A 8-pin steel tube base; EA766 – Diode, 5-pin all-glass wire-ended; EA960 – 100 V PIV VHF Diode, miniature 7-pin base; EA961 – 2 kV PIV VHF Diode, miniature 7-pin base
The EL34 is a thermionic vacuum tube of the power pentode type. The EL34 was introduced in 1955 by Mullard, who were owned by Philips. [1] The EL34 has an octal base (indicated by the '3' in the part number) and is found mainly in the final output stages of audio amplification circuits; it was also designed to be suitable as a series regulator by virtue of its high permissible voltage between ...
The 6N2P, (Russian: 6Н2П), also sometimes spelled in English "6H2Pi", is a miniature 9-pin dual triode vacuum tube manufactured in USSR, Russia and China with characteristics similar to the 12AX7.
