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.
The B7G (or "small-button" or "heptal") seven-pin miniature tubes are smaller than Noval, with seven pins arranged at 45-degree spacing in a 9.53 mm (3/8th inch) diameter arc, the "missing" pin position being used to position the tube in its socket (unlike octal, loctal and rimlock sockets). Examples include the 6AQ5/EL90 and 6BE6/EK90.

Two or more elements in a single envelope were handled by adding letters after the heater identifier, in alphabetical order, so an ECH35 is a 6.3 volt heated triode plus a hexode with an octal base; a PABC80 is a Noval 300mA series-heater combination of a single low-power diode A, a pair of diodes with common cathode B, and a triode C.

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 6П7С (6P7S) is similar to Г-807, but with an 8-pin octal base. The 807 also found some use as a horizontal output tube in early TV receivers, particularly those manufactured by DuMont . The 807 design (with some " value engineering " to reduce production cost) was the basis for the first application-specific horizontal sweep tubes such ...
