Marantz MA-7A 180,000yen(around the 1994 time)

Not a mechanism but monophonic power amplifier of the music linking series which put the viewpoint on music play capacity and was developed.

The power MOS FET strong against a high order distortion is adopted as an output stage with the parallel push pull stream composition, and the output of 30W by a pure Class-A is possible.
Moreover, the power-source part is strengthened so that the speaker of a low-impedance can also have and drive a margin.

The copper plating chassis and the gilding input/output terminal are adopted.
