Abstract
UNDER certain conditions, audio amplifiers with feedback may exhibit instability at low frequencies, which is not predictable by conventional linear analysis. This instability caused by nonlinear effects can occur when the final stage is in class B operation and is preceded by a variable-gain stage, such as a pentode or tetrode.
