This baby is a 1973 SA 9100 integrated amp, this was about one of the worst I have worked on in years I initially thought it was a goner but the look of disappointment changed my mind and proceeded anyway. It was in a shed for over10 years was rusty and corroded . After cleaning and preparing all oxidized metal. Then came rebuilding the wires were cracking in my hands when barely moved,replaced them, and all transistors and capacitors.cleansed all controls and switch's. This gentleman wanted the rebuild and he got it! Premium Low noise Metal film capacitors and all the years of experience tell me the transistors that are known to cause problems, in this case all Bottom line it sounds better then what would have been expected. almost magical LOL restored by Wayne @ Irions
