6L6 is the designator for a beam power tube introduced by Radio Corporation of America in April 1936 and marketed for application as a power amplifier for audio frequencies. The 6L6 is a beam tetrode

Tube sockets are electrical sockets into which vacuum tubes can be plugged, holding them in place and providing terminals, which can be soldered into the circuit, for each of the pins. Sockets are des

…over glass envelope tubes were smaller size, ruggedness, electromagnetic shielding and smaller interelectrode capacitance. The 6L6 incorporated an octal base, which had been introduced with the GE metal tubes. The 6L6 was rated for 3.5 watts screen power dissipation and 24 watts combined plate and screen…

Because of the ubiquity of the octal socket, many other components used it for their pin configuration including relays (not shown), vibrators (top), crystal oscillators (bottom) and small-signal transformers (not shown)
