ABSTRACT:
A horizontal output stage including a switching device for coupling the input of the horizontal output transistor to a feedback network and bias means during startup and to the secondary of an interstage coupling transformer during steady-state operation. During startup the output transistor operates in an oscillatory mode thereby developing an alternating current in the flyback transformer. The supply voltage for the horizontal oscillator is derived from a winding on the flyback transformer. Once this supply voltage reaches the value required for sustained operation of the oscillator, the switching device disconnects the output transistor from the feedback network and couples it to the interstage transformer so that the output transistor is driven by the signal developed by the horizontal oscillator.
