On the schematic, you will find two identical ladders—R-2R resistor networks or dedicated DAC chips (like the classic DAC0808). One is for the X-axis (horizontal deflection), and one is for the Y-axis (vertical).
Different CRTs have different deflection sensitivities, which refers to the specific voltage required to move the electron beam a certain distance across the screen. A well-designed schematic must account for the specific tube’s datasheet, ensuring the deflection amplifiers are properly biased and tuned to provide a clear, centered image without overdriving the plates.
