Max, you do a very good job of detailed explanations of problems, how you fix the problems, and how you test for bad parts. This is very helpful to us at home trying to repair our pinball machines. Thanks
In part 2 I checked all of the power supply caps for proper capacitance and leakage and they were all good including the big lamp cap. From a preventative maintenance standpoint it certainly wouldn’t hurt but if they are still working properly there isn’t an immediate need to replace them.

Glad I can be of help!
You have to replace all the electrolytic in the power supply including the very big one.

The Williams logo? That is an upside down Motorola logo - they are very similar.
You have to look at the Powers’s-ply
I did that in part 2 before I turned the game on
