Output amplifying circuit
 An output amplifying circuit which comprises a Push Pull amplifier section, a power supply circuit section and an amplifier section for amplifying a power source. The circuit eliminates an occurrence of switching distortion and minimizes heat loss therein. The input terminals of the Push Pull amplifier section and the power source amplifier section are connected in common, while the positive and the negative terminals of the power source amplifier section are connected to those of the power supply circuit section, respectively.
