A two-step symmetric amplifier consists of the first current source having leads connected with an electric induction current circuit that made on the fifth-tenth and twenty ninth and thirtieth transistors, accordingly, an input bus, which united with bases of the thirty first and thirty second transistors, and with first leads of feedback resistance and correcting condenser. Collectors of the thirty first and thirty second transistors are united and connect with a neutral bus, their emitters - with bases of the first and the second transistors accordingly. Bases of the first and the second transistors are connected with the electric induction current circuit and with bases of the fifteenth and sixteenth transistors.
