An SCR Horizontal-Sawtooth-Current and High-Voltage Generator for Magnetically Deflected Picture Tubes

The basic principle of a new solid-state deflection system is described as it developed from previous known principles. The new circuit operates from the rectified line voltage and uses as switches silicon-controlled rectifiers (SCRs) in combination with short-lifetime silicon rectifier diodes. The description of the basic circuit follows its adaptation into a color television receiver with its associated auxiliary circuitry.
