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 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.

Electrical cord for powering a block heater. A block heater is used in cold climates to warm an engine prior to starting. They are mostly used for car engines; however, they have also been used in aircraft engines. The most common design of block heater is an electrical heating element embedded in the engine block.
Induction heating is a non contact method of heating a conductive body by utilising a strong magnetic field.Supply (mains) frequency 50 Hz or 60 Hz induction heaters incorporate a coil directly fed from the electricity supply, typically for lower power industrial applications where lower surface temperatures are required.
The 6AQ5 [1] (Mullard–Philips tube designation EL90) is a miniature 7-pin (B7G) audio power output pentode vacuum tube with ratings virtually identical to the 6V6 at 250 V. [2] It was commonly used as an output audio amplifier in tube TVs and radios. It was also used in transmitter circuits. [3]
