Ive been comparing the photos ive received with the transformer i have here and i think its a 110v transformer only as i cant see the other lugs to adjust the input voltage.    Would a non export game have a 110v transformer only as this machine doesnt have the adjustment plug and it doesnt look like it ever did?

This is quite probable as it would require additional tappings on the transformer winding to allow it to be switched from 115v to 240v.  This would add to production costs of the transformer, so maybe they only fitted the 115 to 240v on export models??  However it is a bit hard to tell from the pictures as they are not totally clear.  Is it possible to take more pics of the trany from differnt angles and take them of all the wires.  Maybe able to tell then.
