Super-Emitron

Ref. T2

The Super-Emitron tube was developed by the English EMI (Electrical and Musical Instruments Company) by Isaac Schoenberg and Sydney Rodda in the mid-thirties and was first used in London in 1937. It claimed over ten times more light sensitivity than the original Iconoscope made by RCA.

Super-Emitrons (or similar) were then built in different European countries. They continued to be in use through the late forties until the advent of the Image-Orthicon tubes followed some two decades later by the Vidicons.

The tube shown above is Russian made and bears the Model Number “Li 7” and the serial Number 6221.
