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. Brimar introduced this glass tubular Type in 1938.
Our other Brimar 6V6GT was made in England, this later sample shows manufacture moving to lower cost factories abroad.
The valves were capable of push pull use but the normal environment was as a single end output stage.
The internal coating hides everything. The electrodes can be seen emerging in a line from the miniature pinch.
The wide glass tube envelope is 28 mm in diameter and, excluding the IO base pins, is 68 mm tall.
References: Datasheet, 1040 & 1043. Type 6V6GT was first introduced in 1937.
