Sansui -mid-range model of the early 80s (1981-84). Provides 50 watts of output power at 8 ohms twice. Thanks to Sansui 's super Feedforward system, few distortions. To select the input source by push-button switch, LEDs indicate the respective active input source. Often sold in the UK in a set with KEF Coda III speakers.
AU-D33 was one of the best amplifier from Sansui and from the market in that period.
