Sansui's BEST amp ever made. This is hands down the greatest along with the 11000A amp. Have gone thru many amps until I found this! You'd be hard pressed to find a finer piece of gear than this one here! If your lucky enough to find one grab it you will not regret it - best purchase I ever made- they don't make them like this anymore - sweet Sansui tube like sound that will never come back again.



re: AU-9900A

Lots of 2SA798 dual PNP transistors in these units. Many of these components develop the
creeping black crud on their leads that cause noise and DC imbalance in the main amps. Be careful !
