Sansui AU-919 (1979)
A high-end integrated stereo amplifier released internationally in 1979, identical to the domestic flagship AU-D907.
Overview
The Sansui AU-919 is an integrated stereo amplifier produced in 1979 by Sansui Electric Co., Ltd. It served as the top-of-the-line model for the international market that year, representing the peak of Sansui's global amplifier offerings outside of their AU-X series and high-end separates. The AU-919 is functionally identical to the Japanese domestic flagship, the AU-D907, which was the second generation of Sansui’s 07 Series that began in 1976 with the AU-607 and AU-707. While newer models like the AU-719 appeared internationally after the AU-919, they used older technology, underscoring the AU-919’s advanced position in Sansui’s 1979 lineup.

Design
The AU-919 shares its internal design completely with the domestic AU-D907, positioning it as a flagship-grade unit. Service documentation notes that during disassembly of the heat sink, inspection or repair of the equalizer amplifier circuit may be required, indicating the presence of a dedicated equalizer amp stage in the signal path.
Context
In 1979, Sansui positioned the AU-919 as its premier international integrated amplifier, above models like the AU-517, AU-717, and AU-719. Despite the later introduction of the AU-719, that model used older technology and was not a successor to the AU-919. The 07 Series, which began in Japan in 1976, evolved into this second-generation flagship form with the AU-D907 and its international counterpart, the AU-919.
