You can also contact McIntosh directly. I got one for my MA5100 a couple of years ago. Also, dont know where you live but there are a number of good techs around the country that can check out your new piece and make sure its up to spec as well as do any work needed to get it there. I also have a MC250 which was gone over by a tech in KY or TN before being shipped out to Hawaii. McIntosh is a great investment piece so you might find it worth the while to get it checked out before running it. Usually once you do that you can just run it for another 20 years.
