Hello, and welcome to Beoworld. Your Beocenter 2200 would have been fitted ith an MMC5 originaly. There is only one place you can get new ones and that is www.sound-smith.com . However they are not cheap, the other alternative is try looking for a second hand one, However you may be buying one that is no better than the you already have.
