The differential amplification, the pure complimentary, and the whole page hardwired-connection OCL circuitry are acted on a circuit system.
The transistor of the perfect pair chosen for choosing it as the differential-amplification stage and the output stage of a push pull is adopted, and it is adjusted so that the basic circuit itself may balance completely in direct current.
In the case of high power amplifier, when level is small, in order to carry out the operation near B class, a notching distortion peculiar to a transistor had occurred.
In order to cope with this, sufficient idling electric current was sent, AB class operation was carried out, and the nakedness property even when he has no feedback, to the extent that it is valid is realized.
A substrate is made to become independent for every block, and the interference of the first rank and a final stage is avoided. Moreover, even if it uses an earth line, the thing thick enough is adopted.
Two smoothing capacitors of 60V20000micro F are adopted as a power-source part.
