Jeff,
There will be a few things that need to be changed...
The main AC fuse which would have been a 7.5amp must be changed to a 4amp.
The main AC varistor must be changed to a 275v one (or it'll go bang!)..
http://www.firepowerpinball.com/downloads/PowerWiring.pdfA jumper wire needs to be installed AFAIK between pins 2 & 5 and the old jumpers removed.
I have some spare varistors and if you get stuck I can do it for you Saturday morning..
Its a good idea once you've unpacked the machines to do a very good visual inspection of the existing cord, and all wiring to coils and plugs and ensure the boards havn't worked themselves loose either!.
Hopefully one of the guys with either machine can quickly check to make sure I'm on the right track.
