Good to see a fellow Swede, just wish it were for a nicer reason...

Ouch... There's a thread somewhere on the BBS with a guy that did something similar - attached an AC power supply (from some computer speakers IIRC).

There can be multiple problems - fried components, burnt off copper traces etc...
Had you been in the US I'd have said to send it to Eutronix (se S/PDIF link at top of page), but here in Europe Rob S. is probably your best bet - though he's going through personal problems, which, together with what I suspect is a sizeable backlog, is why you haven't heard back...
