Fantastic...replaced the fuse (only had a fast-blo) and we now have a WORKING pinball machine! 

Ran through all the tests and everthing seems to be working properly (except that I don't have flippers on it yet - waiting for parts).

Only thing is I have most of the sounds but not that strange background sound - maybe I need to change the settings.

Anyway, great result - thanks to Strangeways and Retropin.
