The 6J5G is a single triode is housed within a glass envelope. The electrode assembly is formed on a glass pinch in the traditional style. The anode plates are formed to leave an oval cavity for the grid and cathode.
This exhibit is the Cossor version of the design. We also have the Brimar version 6J5G, the later glass tubular version 6J5GT and the American metal version 6J5 within the museum.
The classic envelope is 36 mm in maximum diameter and excluding the IO base pins the valve is 85 mm long.
