| Description |
Developed in 1939 by W.H. Aldous and J. Bell of GEC, this was the prototype of a wide family of 'micropup' power triodes capable of operation roughly from 200 to 300MHz.
E1046 is the GEC experimental code approved as VT90. According to Clifford Paterson early productions was planned by R. le Rossignol at GEC from September 1938. Production of 100 units per week was planned, starting from October 1946. Actually volume production was slightly delayed due to insulation issues at high altitude which were readily fixed.
The tube had been designed for the transmitter section of AI and ASV airborne radar sets.
