The Integrated Amplifier which investigated the orthodox school which adopts a large-sized toroidal transformer and exceeds a class.

The large-sized toroidal transformer with few magnetic flux leaks is adopted as a power-source part.
Moreover, by adoption of low impedance volume, the impedance of the volume control circuit was lowered and the S/N ratio in a general listening level and aggravation of the frequency response are prevented.

The play which carries the tone control circuit, and reinforcement of a low-pitched sound region or upper register is possible, and also is powerful with a loudness also at the time of small volume makes it possible.
Moreover, the sauce direct switch is carried, by turning ON this switch, a tone control circuit is eliminated and the high play of reliance purity is enabled.

The wide-range equalizer amplifier in which a MC/MM change is possible is carried.
