ected to a device of low impedance in which case the (hs-tortion produced when a simple circuit is used may be considerable.The way in which the push-pull circuit eUminates the chstor-tion can be understood by referring to Fig. 83.

A, except that, since the potentials on the grids of the two tubesare 180° out of lohasc, the fundamental currents ee in the two-plate circuits will differ by 180°, while the harmonics // will be inphase. It will therefore be seen, by referring to the curicntdirections in Fig. 146, that…
