Hang on i just noticed the large white Resistor on the rectifier board is f**ked by the looks of it and need replacing before you go any further!!
Is that replaceable?
There seems to be something snapped off at VR-1 .. is that important?
Do yourself a favour and read this a few times

Here is a list of the rectifier board fuses. This applies to all generations of Bally power supplies from 1977 to 1985.
◾F1 = 10 amp fast-blo (CPU controlled feature lamps)
◾F2 = 3/4 amp slo-blo (score display high voltage)
◾F3 = 4 amp fast-blo (unregulated +5 volts)
◾F4 = 5 amp fast-blo (solenoids, if game has 2 flippers)
◾F4 = 6 amp fast-blo (solenoids, if game has 3 flippers)
◾F4 = 7 amp fast-blo (solenoids, if game has 4 flippers)
◾F5 = 20 amp fast-blo (general illumination lights)
◾F6 = 3 amp slo-blo (incoming 120 volts AC line power)
