Looks like the Jungle Lord pinball power board I repaired. After repair shown, before pretty much like what you have.

I know some wires may be different but this shows what connectors yours had originally. I think I see 2 thick yellow wires in your first picture but do not see where the other one connects. I do not think it matters for most of the wires because they are not separate traces for each one. I would think your power supply is salvageable.

Just guessing ( confirm my assumption here) but it looks like the one bundled heavy yellow wire is the right half of the 9 pin connector and the one on the bottom connected to the fuses is the left half of the 9 pin connector.
