In this exhibit the 6J5GT triode electrode assembly is formed on a conventional tube glass pinch. The anode plates are formed to leave an oval cavity for the grid and cathode.

The museum has examples of this valve in the classic G version (6J5G)and the WW2 metal envelope (6J5).

The electrical characteristics of each half of the 6SN7 match those of the 6J5.

The wide glass tube envelope is 26 mm diameter and excluding the IO base pins measures 66 mm long.
