Flat CRT Drive Circuit
Figure 18
The CRT panel for the Very Flat CRT's has an SVM circuit to sharpen the transitions from dark to light and light
to dark. The RGB signals are combined and fed to 7860 which performs impedance matching. The signal is
then buffered by 7861. Capacitors 2867, 2870, and 2874 along with diodes 6867 and 6868 act as a
differentiator to separate the pulses for the contrast difference. Transistors 7862 and 7863 drive the SVM yoke.
To ensure the SVM switching occurs at the correct point in the picture, delay lines 5886, 5888, and 5890 delay
the RGB signal to the RGB amplifier.
