A degaussing winding adapted to be coupled to a first source of varying amplitude alternating current potential develops a degaussing flux in the proximity of a television picture tube during a degaussing interval. A secondary winding coupled to the degaussing winding supplies current to a power supply network to develop a first direct current potential during the degaussing interval. A further aspect includes means coupling the first direct current potential to a horizontal oscillator to enable start-up of the horizontal oscillator which provides for the development of a second direct current potential by the horizontal deflection system. The second direct current potential is coupled to the horizontal oscillator and sustains operation of the horizontal oscillator after the start-up interval. |
