Abstract
A brief résumé of Heising´s modulator theory is presented together with a discussion of the class B operation of tubes in a push-pull audio-frequency circuit. Several cases of commercial applications of class B audio amplifiers are mentioned. Several general problems involved in the use of a class B audio amplifier are discussed with the conclusion that such an amplifier will produce more audio power for a given tube complement, at higher efficiency, and with less distortion than amplifiers previously used in commercial applications.
