This listing is for a single 6Y6GA tube.

This Tube Test NEW 100% and Passes life test.

Unlike most 6V6's this valve has a glass disc base, like the all glass valves, and not a pinch. It is interesting to note that the original metal 6V6 also had a glass disc base, and only the glass valves that followed the original metal valve used the older pinch construction. The EL34 introduced in 1954 also has the same style of glass disc base with lead-out wires going into the IO plastic base rather than directly to pins. It is probable that this valve was designed in the late 1940s or early 1950s.

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, and one of the first valves on an IO base. 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 27 mm in diameter and, excluding the IO base pins, is 62 mm tall. Type 6V6GT was first introduced in 1937.
