This can make service more complicated off the bat, as everything uses common voltages on a switch matrix. However, I have found (sadly, through first-hand exp.) that Twilight Zone is VERY picky about what it gets for voltage.Case in point: Put mine on a variac, cranked the AC to like 135V, it runs great, go below 117, start a game, hit both flippers, it shuts down. At this point, anyone out there with Williams pin experience says to change the two bridge rectifiers that control the flippers. That was done, not once, but twice.(just in case) At that point, with the machine STILL not working, we changed out the entire power driver board. (Brand new). STILL not working. Now we've gone into checking the wiring, coils, etc. Maybe find a problem there? I have heard that both Twilight Zone and Dracula are the two pickiest pins out there for line voltage. So my suggestion to you would be to throw a meter on your wall line, and make sure your home will support a TZ before you are (Potentially) disappointed. I am not saying they are ALL like this, but my personal experience with this one has been a nightmare.
