The 6V6 family of beam tetrodes came in many constructions and were very popular as the final audio stage of broadcast receivers. The GTY suffix indicates a glass tubular bulb with a wood loaded phenolic resin base.
The GTY version would perform better in humid conditions - possibly in airborne applications.
The valves were capable of push pull use but the normal environment was as a single end output stage.
The Tung-Sol name and the anode seen with the grids in-line above the top mica. The electrodes are seen to be close to the base as a pressed foot is used in the construction. Our other 6V6GTY has conventional pinch construction.
The wide glass tube envelope is 28 mm in diameter and, excluding the IO base pins, is 69 mm tall.
