Usually I can find anything with Google, no luck. But on the Raven Labs site this, these guys are doing the servicing and repair for Raven Labs gear. They may have what you need or be able to suggest a replacement since all Raven Labs gear use the same adapter, there's a good chance they'll have what you need.
