Abstract

This TV receiver power supply is of the type wherein power to operate the audio output stage is taken from the horizontal output deflection circuit. To prevent interaction on the high voltage supply when high audio output levels are reached, the invention provides a compensating circuit arrangement which prevents any lowering of the high voltage during high audio peaks. This prevents noticeable changes in the TV picture width during audio peaks.
