Transistorized Deflection Circuits for 110° Picture Tubes

There has been a long term trend in Television receivers toward larger and brighter pictures, with shorter picture tubes. This hag meant higher anode voltage and ever increasing deflection power for wider angle scanning. The tubes in the scanning circuits of TV Receivers are now required to handle peak currents and voltages that are commonly associated with much larger transmitting tubes. Consequently, the reliability of the tubes in deflection circuits has been a significant factor in the over-all reliability of TV receivers.
