Hi John,
this question come up a LOT...in the US, contact your local B&O shop and order part #898127. $50 + tax & S/H. Since it is not a part made in DK by B&O, they may have to jump through an extra hoop or two to get it for you, but they're available. This gives you a dc power supply, and the connectors you need to make it work. Let me know if you have any other questions.
