English Electric The John Lawrence Collection

The 1971 English Electric data book describes the C1150 as a pulse amplifier tetrode. Stig Comstedt has supplied information that the C1150 and C1111 were used as pulse modulators for Radar magnetrons. He encountered them in the 1960's when serving in the merchant marine.

The maximum anode dissipation is 60 Watts and the pulse power output is 205 kW. The maximum DC anode voltage is 17.5 kV and the maximum pulse current is 15 Amps.

The ceramic insulators are present because of the high operating voltage. The anode being connected to the top cap is also for reasons of insulation of the high voltages.

The wide glass tube envelope is 60 mm in diameter and, excluding the B4A base pins is 130 mm tall.
