the Integrated Amplifier which aimed at the high quality & casuals which can be enjoyed until visual from an audio.

The power stage which had adopted IC excellent in S/N and the distorted characteristic as the drive stage, and uses Pc60W [ large ] of a capacity and a fT20MHz power transistor for the last stage is constituted.

In order to reproduce the character of all sound sauce obediently, while achieving simple-ization of circuit composition, the mother board chassis layout which pursued the arrangement of a part and idealization of wiring is adopted.

The strange continuous loudness control which served as the tone control function is adopted as sound quality regulation.
It is the feature that there is no degradation of a distortion seen in a general tone circuit, and operation is stable.
