Looking for 12V charger for a Bose SoundDock speaker

Hi,

I am looking for a 12V charger for a BOSE SoundDock speaker. It needs 1A at +18V and 1 A at -18V. The input at the back has 4 little pins (it's not a standard DC in).

Do you know whether such a charger exists?

I took photos of the item and of the electrical label at the bottom. I don't know whether I can share these on this forum.

Look for a replacement on Amazon or EBay.

Most off the shelf chargers have concentric +X volt and 0 volt connectors. Different size plugs for different devices. Bose, like Apple, use their own configurations to stop copy-cats.
