Electrostatic deflection is quite good and energy efficient for small sized screens, only a problem for screens a lot larger than 5". All the small 1" sized viewfinder CRT's that turned up in video cameras in the 80's, were mag deflected.

The CRT was made by Telefunken, the type is D5-100WB. It also existed in a green version: D5-100GH. The heater is 0.55V at c. 60 mA.
The MTV1 has the same CRT.
