The Sovjets used 220 Volts, 50 Hz. Due to the lack of suitable television valves, they used different filaments voltages. That's the reason for the large mains transformer. The horizontal frequency is 8,575 Hz. Video bandwidth is appr. 1 to 1.5 MHz.

EHT is generated in the line output circuit, but there is no damper.
