My AU-X1 blew up twice. Once at home and then again on the repairman's bench just after he had spent several month "overhauling" it and was in the process of testing his handy work (it was a huge bummer for him). Now neither one of us want anything to do with it. All of my other Sansui gear has been wonderful: AU-G99X, TU-X1(needs repair but works), AU-D7, and SS-20 headphones.
Sansui AU-X1
Are there any other vintage Sansui enthusiasts out there who might own this integrated amp or knows someone who does or is just particularly familiar with the model?
I am trying to get more background information regarding the stability of its circuit design. It was THE top line model when it first came out in 1979. 160 Watts. Matching tuner was the highly regarded TU-X1. The amp is VERY sophisticated. In fact, I think too sophisticated for its own good. The problem being its tendency to blow up alot of components on the Driver Board and take out all the power output transistors as well when it suddenly goes into Oscillation. (I was told some models by Phase Linear exhibit this unpleasant tendency too- even worse).
If anyone knows if this was/is a common problem with the AU-X1 or has any other information- Please let me know either here or via email: [email protected]
Thanks, Fred (New York).
