SANSUI AU-20000
280,000yen(around the 1977 time)

Description
 
The Integrated Amplifier which carries built-in, in addition a maniac attached functionality for high power and the substantial basic performance.

The whole page hardwired-connection pure complimentary OCL scheme which adopted the triple push pull output stage and made the Oide power and a low distortion possible.

CR+NF type equalizer loading of 2 amplifier stream compositions.

A triple tone control functionality is equipped.

The tone defeet from which a flat property is acquired.

The large-sized power-source part which uses a highly efficient toroidal transformer and a stabilization circuitry.

The switching possible of Input sensitivity/impedance.
