6V6 Octal socket basing diagram. 1 - * Unconnected in all versions except for the shell connection of the metal 6V6 2 & 7 - Filament / Heater 3 - Anode / Plate 4 - Grid 2 / Screen Grid 5 - Grid 1 / Control Grid 6 - No connection. Pin normally absent 8 - Cathode & Beam-Forming Plates. The 6V6 is a beam-power tetrode vacuum tube.
High-power RF power tubes are directly heated; the heater voltage must be much smaller than the signal voltage on the grid and is therefore in the 5...25 V range, drawing up to hundreds of amperes from a suitable heater transformer. In some valve part number series, the voltage class of the heater is given in the part number, and a similar ...
The transmitting tubes TT21 and TT22 have almost identical transfer characteristics to KT88 but a different pinout, and by virtue of their anode being connected to the top cap have a higher plate voltage rating (1.25 kilovolt) and a higher power output capability of 200 watts in class AB1 push–pull.
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 ...
TY86F – 7.4 V, 77 mA heater version of the EY86 18-kV CRT EHT rectifier, [48] for use as a hotfix in early-production Ferguson Radio Corporation TV receivers 306T and 308T [55] where the horizontal-output transformer produced excessive heater voltage which destroyed the originally fitted EY86s.
In common with all 'E' prefix tubes, using the Mullard–Philips tube designation, it has a heater voltage of 6.3V. It can produce 17W output in Class AB1 in push–pull configuration. Many guitar-amplifiers routinely run EL84 tubes in excess of 400VDC, with the Traynor Guitarmate reportedly putting out 25W RMS with 2 EL84s in a push–pull ...
The beam tetrode produces greater output power than a triode or pentode with the same anode supply voltage. [3] The first beam tetrode marketed was the Marconi N40, introduced in 1935. [ 4 ] [ 5 ] Beam tetrodes manufactured and used in the 21st century include the 4CX250B, KT66 and variants of the 6L6.
