<p>In a switched-mode power supply for a television receiver, the great change in operating current (i2) for the audio signal stage (15,16) has an interfering influence on the magnitude of the operating voltage (U1) for the line output stage (12), thus on the picture width. This influence is reduced by a resistor (22) in series with the rectifier (11) for obtaining the operating voltage (U2) for the audio signal stage (15,16)(Figure 1). <IMAGE></p> |
