Rick, I got back on eBay and found another changer. This one was about $150 and the seller listed it as "one owner" and excellent condition. The destroyed one was manufactured in May 2004 and this one in April 2002 (happy 20th birthday). This time the machine arrived undamaged and as I suspected, it needed carousel and changer belts. The original belts have turned to black tar, which refused to come off with paint thinner so I attacked them with lacquer thinner.

I was able to get the disk changer belt pulleys (on the right) cleaned in place and the new belt installed. The carousel Belt drive pulleys were much worse so I removed the driven pulley and cleaned it on the bench. Really glad I bought the Costco pack of 3,000 Q-Tips.

Before I put the covers back on I tested the machine and it is running through all its cycles just like the one I bought 20 years ago.
Scott, I am shocked and disappointed every time someone pulls a stunt like that. I can't live in fear of the bad guys so I get taken advantage of every once in a while. My only revenge is to waste as much of their time as possible. I love the calls from the "I'm from Microsoft and we see your computer is infected with a virus. We can remove it but you have to give us permission to access the machine...." scam. The tenth time I say "I don't understand your instructions, could you repeat that?" they seem to disappear.
