Power Supply Unit

Like all other electronic measuring apparatus, cathode ray oscilloscopes are mostly designed for AC mains operation. A suitable rated mains transformer supplies all the necessary voltages on its secondary side. The tubes are generally heated by AC, which is also supplied from suitable secondary windings. The heater windings for E.H.T. rectifier valves and cathode ray tubes must be provided separately and be suitably insulated, as they are at a very high potential with respect to the chassis and to other windings.
