Marantz SC-23 120,000yen(around the 1994 time)

The preamplifier of the music linking series which put the viewpoint on the music play capacity instead of a mechanism, and was developed.

The line amplifier of 14dB gain is adopted so that power amplifier can be driven with a margin.
Moreover, an input system is limited only to four lines and one input for tape decks, and has the simple stream composition.

By each output of a right phase and negative phase, a by amplifier drive of power amplifier and the BTL drive are possible.

The output circuit serves as an original output transformer scheme which adopted the transformer joint multi-feedback circuit.

The toroidal transformer and the copper plating chassis are adopted.
