  • Notes
  • The Type 420 High Voltage Power Supply is an oscillator type supply similar to the Type 210. It is designed to provide the potentials for the special high voltage cathode ray tubes which are used in the Tektronix Type 517 High Speed Oscilloscope.
    The Type 420 uses a versatile voltage quadrupler type of circuit. Greater flexibility of operation is mode possible by using separate transformers for both the filament and high voltage supplies. This permits varying the high voltage, without affecting the filament operation, by varying the excitation of the high voltage oscillator.
    Outputs: 20KV, @ 200uA, -4KV @ 700uA
    Dimensions: 6 3/4" diameter, 10" high.
