The

SANSUI AU-2000
41,800yen(around the 1973 time)

Description
 
The Integrated Amplifier which supplied the audio technology of the SANSUI.
It is the structure which inherited the technology of the high order model.

The large-sized transformer is adopted as a power-source part.

The amplifier part consists of semi- complimentary Darlington SEPP-OTL circuitries.
Moreover, the fuse for a power transistor protection is adopted.

Functionalities, such as the selector of tuner priority, a row / high filter, a loudness, a tapes monitor, a mode switch, and three kinds of speaker switchings, are carried.

The mic jack and the DIN termination are carried in the front panel.
The high impedance type mic is supported.
