AB  - An add-on facility for audio power amplifiers is described, by which nonlinear distortion products in the audible range of frequencies are reduced by a typical 25-30 dB. The improver uses the principle of nested differentiating feedback loops to increase the feedback around the amplifier. The improver also corrects phase nonlinearity in amplifiers, improves loudspeaker damping, increases isolation between stereo channels, and reduces hum, noise, and dc drift.
