Absolute dream condition and also the extremely rare 240V version. 40kg live weight and a processing par excellence! At this point we leave sounding hymns of praise, We certainly do not have to convince Sansui enthusiasts any more. The Sansui AU-Alpha 907DR comes from the collector's hand, has only a very small scratch ( picture no. 10 ) and is practically in a new condition!
