ABSTRACT:
A DC feed-back circuit for causing a DC voltage of an external transistor in which an output bias current of a record amplifier flows to be equal to a DC voltage of an output terminal is provided so as to decrease power consumption. Thus, a plurality of record amplifying circuits can be incorporated into one IC chip. In particular, in home-use Hi-Fi VCRs, a Hi-Fi record amplifying circuit and video record amplifying circuits can be incorporated into one chip.
