ABOUT THIS ITEM

The Sansui AU-999 is a solid-state integrated amplifier made in Japan by Sansui, one of the most respected names in vintage audio, produced from 1970 to 1972 during the golden era of Japanese hi-fi as the top model of Sansui's 9-series. It delivers 50 watts per channel into 8 ohms (70 watts into 4 ohms), with 180 watts of music power into 4 ohms. The power amplifier section uses a direct-coupled circuit with a two-stage differential amplifier and dual positive/negative power supplies, eliminating the output capacitor for improved tonal quality, while the preamplifier section is built with carefully selected low-noise PNP silicon transistors. It is lavishly equipped with accessory circuits, including an improved triple tone control with a tone selector that lets you choose the turnover frequencies for bass, midrange, and treble, high and low filters, two phono inputs and two tape inputs, a three-way speaker selector, a balance-check switch, and a separable pre/power amplifier. Robustly built, the AU-999 remains a refined and highly sought-after vintage integrated amplifier.
