The 6V6 family of beam tetrodes came in many constructions and were very popular as the final audio stage of broadcast receivers. The original 6V6 was an American metal can valve from the mid 1930s.

The valves were capable of push pull use but the normal environment was as a single end output stage.

The wide glass tube envelope is 28  mm in diameter and, excluding the IO base pins, is 70 mm tall.
