Abstract
A television receiver includes an integrated circuit audio amplifier for having an inverting terminal, a noninverting terminal and an output terminal connected through a feedback resistor back to the inverting terminal. A first capacitor is coupled to the noninverting terminal and a second capacitor is coupled to the inverting terminal. A voltage divider normally establishes the first capacitor at a given potential. A source of regulated potential less than the given potential is coupled through a pair of series connected diodes to the first capacitor and through a single diode to the second capacitor, thus establishing two separate charging paths for said capacitors with the initial time constant of the path coupled to the noninverting terminal being longer than the initial time constant of the path coupled to the inverting terminal.
