A Transistor Vertical Deflection Circuit Employing Transformer Coupling

This report contains a description of a two transistor circuit which provides vertical deflection for a 110° kinescope operating at 18 kilovolts. The effect of various transistor characteristics on the operation of the circuit is discussed. The factors affecting the stability of the circuit under varying conditions of supply voltage and temperature are considered. It is concluded that with the exception of retrace time the circuit performance is comparable to conventional tube circuitry.
