Reports

  • Report in "FonoForum" 7 / 1991


  • External differences to the A-656: smaller knobs replaced by cylindrical versions resembling the large knobs.
  • Golden dot only on the volume potentiometer.
  • Inside: still horizontal circuit boards, but already no honeycomb housing around the volume potentiometer at the back right of the unit anymore
