Marantz MA-23 90,000yen(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 output of 50W is secured by AB class, and the margin is given to the power-source part so that it can drive also with the speaker of a low-impedance.

The copper plating chassis metallurgy plating output-terminal is adopted.
