Abstract
A driver stage of a horizontal deflection output transistor includes a transformer having a first winding coupled to an input signal at a horizontal deflection frequency, a second winding coupled across a base-emitter junction of the output transistor and a third winding coupled to the emitter of and in series with the output transistor. The third winding couples the emitter current to the base of the output transistor for supplying a substantial portion of the base current during the second half of trace.
