Williams Phoenix Pinball Restoration Part 3: Fixing the Lamps, Drop Targets, Sound & Flippers

In part 3 of the 1978 Williams Phoenix restoration series I figure out the cause of the loose flippers, fix the CPU controlled lamps that were not working, solve various drop target problems, and get the sound board to start producing sounds.

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

Glad I can be of help!

On the sound board, have you re-flowed the solder on the back of the connectors? Maybe repinned the female connector wires? Intermittent stuff or “works when I poke it with a stick” issues are usually connector issues.

You have to replace all the electrolytic in the power supply including the very big one.

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.

You have to look at the Powers’s-ply

I did that in part 2 before I turned the game on

The Williams logo? That is an upside down Motorola logo - they are very similar.
