Never seen that before. If you post it to me we'll check it out for you.

Looks like those Diodes are to protect for reverse polarity power connection? Could you have reversed the power connection at all?
In theory if you have power to both banks of the input power it won't matter that the track has been burnt out.
2 things of concern though.
-36V is right on the maximum 36V that the OKI78SR regulators can handle.
-there are a couple of possible reasons that the track fused. The 1 I'd be most concerned about is the jumpers to select the input voltage. If that happened to have been in the 5V setting you may have damaged all sorts of things which could present a short circuit and potentially fused the track.

The regulator is not an OKI one. It's an LM2575, so not sure what has happened there.
Good point about the jumpers. If they were set to 5V, the board will be somewhat toasted.

Send it in and we'll go from there. 
As per my PM, we don't have any ex-stock, but will be making a few more this week.
Other than that, Alan (AAH) may be able to help with an M60 board?

Just an update; we had Kevin's board repaired and back to him the next day.
We do also have a couple of DC48 in stock if anyone needs them.
