Marantz Model 3300 195,000yen( at the 1972 time(?))

Control amplifier which designed the circuitry newly, and the material of sorting of a transistor, a resistor, or switchpoints used for the transistor having selected carefully.

The hardwired-connection circuitry which uses a differential circuit for the first rank is used for the equalizer stage, the tone control stage, and the amplification stage of sending.

Since a power-source part corresponds to the wave of an asymmetrical and intense actual music, to serve also as a ripple filter, it made the power transformer in voltage stabilizer, and has it. Moreover, right and left were made to gain separate independence in the place which came out of silicon diode, and the low-pass crosstalk is improved.
Moreover, the minimum thing of flux is used for the transformer itself which wound the short ring around the transformer using the cut core, sufficient mounting space is taken, and influence is suppressed.
