Crt Clock Schematic -

The schematic looked impossible at first: a low-voltage transformer, a handful of vacuum tubes drawn with neat Victorian loops, a cluster of neon indicators, and—most curious of all—a small cathode-ray tube sketched with a delicate crosshair aimed at a numbered circular dial. Next to the dial the old hand had written, almost apologetically, "Time, as seen."

Finally, the signal reaches the output stage. The voltages from the DACs are precise but weak; they cannot drive the magnetic yoke or electrostatic plates of a CRT directly. The schematic looked impossible at first: a low-voltage
