Abstract :
Distortion in tube amplifiers may be eliminated by using an auxiliary amplifier in which a fraction of the main-amplifier input voltage combined with a fraction of the distorted main-amplifier output voltage produces a correcting component which, combined with the total output, restores this to the same shape as the input.
