I also had an AI preamp, the best phono stage I ever had was in it. I sold it before ever having any problems.
If it's not warranty work I would try Ric at EVS.

He used to build those preamps when he worked at AI. He does not however have a very high opinion of Art and has some rather interesting stories of how Art acquired the company.
