Agape126, I was going on memory sorry for the confusion.
I did just look at the AR website and it says the following: "Owners of CDT1 transports, CD1 and CD2 compact disc players and D52, D60, D100, D110, D111, D120, and D350 solid state amplifiers should email Customer Support at service@audioresearch.com before sending any of these models to Audio Research for repair".
