The CV1932 is a single 6J5G triode housed within a shouldered glass envelope. The electrode assembly is formed on a glass pinch and the anode plates form an oval cavity for the grid and cathode.
The KB/FE identifies this valve as being made to specification K1001 or K1006, the B denotes qualification by a UK authority and the FE identifies the maker as STC Oldway factory.
The triode is far away from the base pins - not a design for high frequency performance.
The triode requires little front to back room.
The classic envelope is 38 mm in maximum diameter and excluding the IO base pins the valve is 85 mm long.
