Gorgeous Sansui AU-11000A & Matching Sansui TU-9900 Tuner ! Both of these just got cleaned, serviced and tested on the bench ! We went ahead and cleaned all of the potentiometer and switches with DeOxit and then lubricated where necessary. Multiple fusible resistors were replaced along with a few diodes and capacitors on the Integrated Amp. The AU-11000A is a very rare model, with a much improved volume knob, better parts, soft start relay and more WPC vs the AU-11000. (slight imperfection to upper right of faceplate that has been touched up) Sansui TU-9900 received a full cleaning as well, DeOxit on switches & potentiometers as well as replacement of and burnt out original incandescent bulbs. tuning alignment performed and then both units tested, sounding incredible !both units will be professionally packed, tracked, fully insured, and delivered to your address within the lower 48 states for FREE. Local pick up on Long Island New York is also more than welcome. Thank you.
The AU-11000A is a serious late-’70s Sansui: 110 watts per channel, hefty build, and the kind of drive and phono stage that made these big integrateds so respected. At US$3,799, the ask looks ambitious rather than fair; for a used piece, that sits at the very top end unless it’s fully restored, documented, and cosmetically exceptional.
What makes it worth chasing is the combination of musicality, power, and vintage prestige—this is one of the Sansui integrateds people buy to actually use, not just park on a shelf. If the unit is clean, original, and recently serviced, the upside is real; if not, a price like this should be justified by proof of restoration, strong cosmetics, and complete knobs/covers, because age-related maintenance is part of the equation.

Sansui, a pioneering Japanese audio brand, traces its origins to 1947 when it was founded in Tokyo by brothers Sakurai and Shunichi Yamamoto. Emerging from post-war Japan, the company quickly established itself as an innovator in consumer electronics, leveraging precision engineering to craft components that rivaled Western counterparts. Its heritage is rooted in the golden era of hi-fi, where Sansui's commitment to sonic purity helped define Japan's rise as a global audio powerhouse.
The brand excelled in a broad spectrum of hi-fi categories, with particular renown for its integrated amplifiers, receivers, and tuners that delivered warm, dynamic sound. Sansui also produced acclaimed speakers, turntables, cassette decks, and later digital converters, emphasizing robust build quality and innovative features like direct-coupled circuitry for low distortion. These products catered to audiophiles seeking balanced performance across analog and early digital domains.
Today, Sansui holds a cherished position in the vintage collector market, revered for its mid-to-high-end gear from the 1970s and 1980s—icons like the AU-series amps remain sought after for their musicality and reliability. While no longer a frontline manufacturer, its legacy endures among discerning buyers restoring classics or hunting timeless performers, blending nostalgia with enduring value.
