The X65 is a triode hexode frequency changer for receiver applications. The X65 is the commercial version of the RAF pre-WWII VR99. The X66 is a selected X65 and also given the CV number of CV1099.The edge of the blue Osram label can be seen on the right of the picture.The triode was designed for local oscillator use and an injection voltage of 10 V peak to peak was produced. The hexode mixer took the signal into the top cap grid, thus maintaining the greatest separation between grid and anode circuits.This exhibit is virtually identical to the X65 in the HMS Collingwood Collection apart from the quality of the lettering.The classic envelope is 37 mm in diameter and, excluding the IO base pins, is 95 mm tall.References: Data-sheet & 1040. Type X65 was first introduced in 1937. See also 1937 adverts. |
