Sansui model AU-9900A integrated amplifier in excellent condition. Acquired from the original owner. It has been serviced and fully tested. Included is our original Performance Verification Report .

The Sansui model AU-9900A is rated at 80 watts RMS per channel into 8 or 4 ohms. It features dual phono inputs, one with adjustable loading. Side I/O locations make for easy cable management.

From Sansui:

The AU-9900A is identical to the superb specifications of the AU-11000A except for a slightly reduced power output.

Features include:

Stabilized, well regulated power source; oversized power capacitors, advanced toroidal transformer, excellent RIAA equalization.

All controls, connections and convenience for professional and semi-professional use.

Technical Note:
The differences between the AU-9900 and AU-9900A that we know of are:

The volume control in the AU-9900A has been changed to logarithmic from linear.
The "Level Set" control located beneath the volume control has been eliminated.
The driver board has been changed to the same type used in the BA-2000.
