The CV172 diode is a specially constructed directly heated noise source. The pressed glass base was developed by Mullard in 1938 and this must date from before the 1941 introduction of the CV system by virtue of its low CV number.
The American Radiation Laboratory commented on noise diodes for measurements on radar equipment that 'the British CV172 is the most satisfactory.
The additional information on this valve was supplied by R J Sutherland.
The wide glass tube envelope is 32 mm in diameter and, excluding the B9G base pins, is 58 mm tall.
