I am making a Standard JAMMA out of all of my spare parts that I had in my closet. It will go in an old gutted Double Up video poker upright cab that I have. I wanted to make a drop in AC power unit (much like The Real Bob Roberts without the $100 price tag).

I had a JAMMA power supply and the AC unit for a Nintendo cab, I pulled the gold box and replaced it with my little black one. I made it look decent and then I got to questioning it. The isolation transformer takes in 120v and puts out 100v. Am I going to need to replace the iso transformer with a 1:1 for it to work in a Standard JAMMA???
On another note, I have never worked with JAMMA before. The only arcades that I have repaired and rebuilt are Nintendo. Do standard arcade CRTs have electrical plugs or are they two holed molex type connectors for the power??? The reason I ask is that The Real Bob Roberts offers a harness to go on the iso transformer and it has a molex type connector where the Ninty version has a lower voltage outlet inside the machine.

I have a number of forks in the road and I am wondering which path would give the best results.
I could change the iso transformer. Then change the outlets to allow for three pronged cords (this would help if I end up installing an computer LCD monitor instead or an original arcade CRT).
I could see if I can locate a Standard JAMMA compatible monitor that requires 100v (if they exist).
I could get the iso transformer and harness from Bob Roberts and call it good.
I am okay with leaving my on/off switch, fuse, and line filter the way they are; correct???
I am starting to think I should have just bought the Bob Roberts delight but I figure I will turn this into a learning experience.
