    en.wikipedia.org/wiki/Tube_socket

    Tube sockets are electrical sockets into which vacuum tubes (electronic valves) can be plugged, holding them in place and providing terminals, which can be soldered into the circuit, for each of the pins. Sockets are designed to allow tubes to be inserted in only one orientation.

    The pentode EL84/6BQ5 - 9 pin Noval base tube, that although different enough from the 6V6 not to justify rating it as an equivalent, because of its popularity and ready availability, plus having a close-enough similarity to make it possible, if bias is altered, adapters have been developed commercially to allow an amplifier designed for 6V6 ...

  5. 12AU7 - Wikipedia

    en.wikipedia.org/wiki/12AU7

    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 ...

  6. 807 (vacuum tube) - Wikipedia

    en.wikipedia.org/wiki/807_(vacuum_tube)

    The 807 design (with some "value engineering" to reduce production cost) was the basis for the first application-specific horizontal sweep tubes such as the 6BG6G and 6CD6G. The redesign mainly involved the omission of some of the internal RF shielding, and the substitution of a bakelite octal base for the micanol or ceramic 5-pin.

    The EIA 7AC pinout. The tube used EIA base 7AC in common with many other power tubes. The tube was identical in design and ratings with the 50L6 with the exception of having a 25 volt 300 mA heater, whereas the 50L6 has a 50 volt 150 mA heater. The 12L6 and identical 12W6 were made with a 12 volt, 600 mA heater, and the 6W6 was made with a 6.3V ...

    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 ...
