Abstract
A circuit for power amplification for an audio amplifier that reduces power supply noise amplified to the load. The circuit takes the prior art circuit's existing output coupling cap and power supply decoupling cap and connecting them in series from the power supply to ground. The output of the amplifier is then directly coupled to the load and the other side of the load is connected at the “null point” between the two capacitors.
