An amplifier stage in a series connection of such stages in a low or medium frequency analog amplifier construction, e.g. for audio, is provided with correction circuitry for dynamic cancellation of non-linearities in the stage output. The correction circuitry includes a threshold detector feeding a correction signal to an adder circuit that is inserted in the series connection. An input signal to the threshold detector is supplied from a junction where e.g. resistors coupled respectively to an input and an output of the stage, meet.
