About the AU-717
The Sansui AU-717 is a Japanese stereo integrated amplifier produced from 1977 to 1979. It combines a preamplifier and power amplifier, with separate power supplies for the two channels, two phono inputs, tone and filter controls, tape connections, and pre-out/main-in connections. Its rated output is 85 watts per channel into 8 ohms with both channels driven across 20 Hz–20 kHz, at less than 0.025% total harmonic distortion.
