Push–pull circuits are widely used in many amplifier output stages. A pair of audion tubes connected in push–pull is described in Edwin H. Colpitts' US patent 1137384 granted in 1915, although the patent does not specifically claim the push–pull connection. The technique was well-known at that time and the principle had been claimed in an 1895 patent predating electronic amplifiers.
