The Sansui AU-217 II is an integrated stereo amplifier that was part of Sansui's lineup of audio equipment during the late 1970s and early 1980s. It offers a conservative power output of 30 watts per channel into 8 ohms, which suits well with a variety of speakers from that era. This model follows the AU-217 and features improvements in circuit design and overall construction, aiming to deliver cleaner, more stable sound reproduction. It typically includes a phono stage, capable of handling both moving magnet and moving coil cartridges, which makes it compatible with a wide range of turntables. The build quality and audio performance of the AU-217 II make it a desirable unit for vintage audio enthusiasts and collectors.
