The CV4084 is the CV4015 fitted with flying leads rather than base pins.
Electrically it is an indirectly heated RF and IF vari-μ pentode for use in compact radio equipment subject to vibration. It is a special quality version of the EF92 design. Vibration resistance is achieved by the use of double mica sheets in the supports.
The KB/DC identifies this valve as being made to specification K1001 or K1006, the B denotes qualification by a UK authority and the DC identifies the maker as Mullard Radio Valve Co., Whyteleafe.
The unused valve complete with long leads for direct soldering into circuit.

The thin glass tube envelope is 18 mm in diameter and, excluding the B7G base wires, is 46 mm tall.
