Aha! Thank you!
So, it seems the sense circuit is designed to automagically adjust the voltage of the power supply if it starts to drift.
I connected sense specific wiring to the power supply along with the others and set voltage to 5.05. Turned the cabinet on and it fired right up!
Well...
Oh man. I just found another thread on KLOV that showed a clear picture of the original power supply. Same form factor as modern switchers, but it has terminals for +sense and -sense. I'm 100% sure that the supply I removed from the machine didn't have that.
