thanks for that, odd thing is the first XM-2001N I came across was from a Blasteroids and has a little red sticker on the frame that says 120V so I assumed they were all 120V. I repaired it, re capped it and put it in my Frogger and because of the 120V sticker, I tapped the 120V on the ISO, it's been in there for 2 years now running fine. My Frogger had a dead Sanyo 20EZ when I got it and a K7000 wouldn't fit in the cab. I ended up putting a K7000 in the Blasteroids with out changing anything else and it to has been running fine for well over a year now. These games are in an arcade and get used almost every day. I have another XM-2001N in my XYBOTs, just out of curiosity I am going to see what voltage it's running at after work today. Maybe the 100V +/- 15% is whats allowing it to run on 120V?
