The 6V6 family of beam tetrodes came in many constructions and were very popular as the final audio stage of broadcast receivers. We have an American rugged metal valve (6V6) and a miniature glass tubular version the 6V6GT. The 6V6 shown here is of the classic glass envelope shape, and unlike the Mullard version in our collection, this Cossor valve has a clear envelope enabling the electrode structure to be clearly visible.

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

The classic envelope is 43 mm in diameter and, excluding the IO base pins, is 100 mm tall.
