The CV1091 is the service version of the EF50. It is clearly a utility valve with its plain aluminium screening can devoid of the familiar red point.The valve is a high impedance pentode and was a workhorse of receivers for both radio and especially radar.The KB/DA identifies this valve as being made to specification K1001 or K1006, the B denotes qualification by a UK authority and the DA identifies the maker as Mullard Radio Valve Co., Blackburn.The wide glass tube envelope is 32 mm in diameter and, excluding the B9G base pins, is 57 mm tall.References: Data-sheet & 1040. |
