I think yours is jumpered right, Rob.

Marty's is the same.

Can you test the transformer with no load - ie. No connections from the transformer to the machine ? The schematics will have the voltages you should be seeing.

My theory (well 2) are:

Power surge / lightening strike has killed transformer and powerboard with surge.  The way it has burnt on your power board looks very much like a surge.

Or something has been spilt on transformer causing an internal short.

Hopefully another transformer will turn up.
