ABSTRACT:
A source of alternating current in a power supply and deflection system of a television receiver is coupled to a primary winding of a transformer, a relatively closely coupled secondary winding of which provides a voltage which may be rectified for providing operating voltage for another portion of the receiver such as the vertical deflection system. Yet another portion of the receiver, such as the audio section, is energized by voltage derived from a winding so disposed around the transformer as to be energized by leakage flux from the transformer for substantially reducing the effects of variations of the audio loading on the deflection systems.
