Stereo Integrated Amplifier (1977-79)
The AU-717 amplifier incorporates an advanced design feature which has extremely low inherent transient intermodulation distortion enabling negative feedback (necessary in traditional amplifier design but undesirable) to be reduced to the absolute minimum.
Power amplifier design too, shows a departure from tradition resulting in the elimination of DC drift.
Differential push/pull amplifier stage eliminates open-loop distortion. The driver stage is 3-stage darlington connected.
