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.
Brimar have marked the valve as Made in England but the etched designation octagon looks identical to the American and the code beneath is in a different fount.
The museum has examples of this valve in the classic G version (6J5G) and the WWII metal envelope (6J5).
The electrical characteristics of each half of the 6SN7 match those of the 6J5.
The face view of the anode with the grid visible top and bottom.
The wide glass tube envelope is 29 mm diameter and excluding the IO base pins measures 66 mm long.
References: Datasheet & 1040. Type 6J5GT was first introduced in 1936.
