The CV118 is a WWII military HF receiving pentode valve. Externally it is covered by an external screening metalisation. It functioned as a mixer with the P61 (VR66) as a low noise oscillator.With the grid at the top cap, this is the normal pattern for RF and IF amplifier valves of the period. Providing high gain in tuned anode circuit applications.This valve type was used in air-borne radar particularly GEE.The classic envelope is 31 mm in diameter and, excluding the MO base pins, is 81 mm tall.References: Data-sheet & 1040. Type CV118 was first introduced in 1941. See also 1941 adverts. |
