ABOUT THIS ITEM

The Sansui AU-666 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 a mid-tier model sitting between the AU-555A and the AU-888, it is renowned for its warm, natural, and highly musical "tube-like" sound. It delivers 35 watts per channel into 8 ohms (45 watts into 4 ohms), with 80 watts of music power into 8 ohms. The power amplifier uses a direct-coupled, fully-complementary Darlington circuit with a two-stage differential amplifier for clean, low-distortion sound. It is generously equipped with two phono inputs for MM cartridges, a microphone input, three-band tone controls for bass, midrange, and treble, high and low filters, a loudness control, muting, and a separable pre/power amplifier, along with connections for two pairs of speakers. Built with Sansui's hallmark attention to detail, a robust all-metal chassis, and a solid aluminum front panel, the AU-666 remains a warm-sounding and highly sought-after vintage integrated amplifier.

・Power Supply Voltage: AC 100V, 50/60 Hz (Japanese domestic model). Please use a suitable step-down transformer in 110–240V regions.
