C1, C3, C5 and C6 are all 25 volt. C2, C4 and C7 are 16 volt.
I don't remember what the bridges are offhand, but I replace everything with 600 volt. I can check these out later if need be. The setup on those bridges on your board is normal, and they might even be stock.... although work may have been done around them.
And for what it's worth, your board is actually a PCA-001 (as the manual drawing shows), and not a PCA-006. Early boards were printed PBPS-001. To make things even more confusing the parts list shows a board number of PCA-006, which was a later generation of board used in some other games.
