Which indicator power supply furnishes the CRT operating voltages?

Explanation:
The voltages that actually drive the CRT’s electron beam come from the high voltage power supply. The CRT requires a high anode voltage to accelerate electrons toward the screen, which creates the image. A low-voltage supply feeds the heater (filament) and other logic or control circuits, but it does not provide the necessary acceleration potential for the beam. Ground is just a reference and isn’t a supply of operating voltages. So, the indicator power supply that furnishes the CRT operating voltages is the high voltage supply.
