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 ...
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.
12AU7. The 12AU7 and its variants are miniature nine-pin (B9A base) medium-gain dual- triode vacuum tubes. 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 ...
The 6SN7 was originally released in 1939. It was officially registered in 1941 by RCA and Sylvania as the glass-cased 6SN7GT, originally listed on page 235 of RCA's 1940 RC-14 Receiving Tube Manual, in the Recently Added section, as: 6SN7-GT. Although the 6S-series tubes are often metal-cased, there was never a metal-envelope 6SN7 (there being ...
The 6V6 is a beam-power tetrode vacuum tube. The first of this family of tubes to be introduced was the 6V6G by Ken-Rad Tube & Lamp Corporation in late 1936, [1] with the availability by December of both Ken-Rad and Raytheon 6V6G tubes announced. [2] It is still in use in audio applications, especially electric guitar amplifiers. [3]
ECL113 – Triode - AF power pentode, Rimlock base. ECL200 – Triode - CRT drive power pentode, decal base, PCL200 with a different heater. ECL802 – Triode - Power pentode for use as vertical oscillator and output tube in TV receivers. ECL805 – Triode - Power pentode with separate cathodes, PCL805 with a different heater.
12AT7 (also known in Europe by the Mullard–Philips tube designation of ECC81) is a miniature nine-pin medium-gain (60) dual- triode vacuum tube popular in guitar amplifiers. It belongs to a large family of dual triode vacuum tubes which share the same pinout (EIA 9A), including in particular the very commonly used low- mu 12AU7 and high-mu ...
