AFAIK, the displays were working at hippochrome's place. Back when it was just the resistor that was busted in the high voltage section, attaching a DMM to the resistor got the displays to turn on, and they seemed to work.
I'd recommend a full rebuild of the high voltage section of the power supply, and go from there.
I wasn't aware that the ramp was installed improperly, nice find.
The game is pretty damn fun, good luck! |
