The Sansui AU-317 II is an integrated amplifier produced in the late 1970s. It was designed to deliver solid performance in audio reproduction with a power rating of 50 watts per channel into 8 ohms. However, due to its robust design featuring 42 VDC rails and two sets of output transistors (2SA745 and 2SC1403), the actual power output is estimated to be closer to 80-90 watts per channel, making it capable of handling a variety of speaker loads with ease. Many users have noted its durability, with some units still operational after decades of use. Restoration and maintenance of these amplifiers are not uncommon, as evidenced by the frequent replacement of electrolytic capacitors and adjustments made to ensure optimal performance. The design aesthetics of the amplifier are also appreciated, reflecting the style of the era. It is often used for audio applications ranging from home audio systems to powering speakers for computers, signifying its versatility and enduring appeal. Owners have highlighted its reliability and the quality of sound it produces, often describing it as a nostalgic and cherished piece of audio equipment.
