DEFINITION

Classification: 315/406

(under subclass 405) Subject matter wherein there is included a diode or additional amplifier to selectively pass current produced by the induced voltages of the transformer or deflection coil, the movement of the current through the diode or amplifier being used as a power source.

(1) Note. The power source may be to supply the second anode voltage for a cathode-ray tube or kinescope or to boost the plate voltage of an amplifier tube.
