Great thread Ken. Figured I'd add to it for future use purposes.
I picked up this Fireball earlier this week that was pretty damn cheap and SUPER clean but didn't work. 5v and 12v were dead and R101 position in the 22v section of the power supply was charred like a mofo. After reading this thread I ended up wiring in a switcher to handle the 5v & 12v and rebuilt the 22v section with new transistor, caps, diodes and resistor. Once all that was done, the damn thing fired right up and the ball was ejected.
All was well except the pop bumpers were awful. Left one worked 85% of the time an right one worked 15% of the time which was determined to have a bad micro switch. The problem with the set up is the spoon switches are mounted to a big pcb under the play field and conventional pop/spoon leafs would not have worked without major modification.
Stock pcb mounted switch.
Got the idea in my head to use a couple williams leaf switches from a defender panel I had kickin around. Cut the spoon portion off the arm of the micro switch and soldered it to the switch that I had bent.
Switches installed.
PCB back in place with switch wires soldered right to board.
Game is actually pretty fun when you have pop bumpers that work 100% of the time.
good day.

That's a good idea you got there!
I had an idea that it looks like it would be possible to 'shoehorn' in a Gottlieb spoon switch assembly such as GTB-22704 or GTB-22704 which are available at Pinball Resource. These are small enough that they look like they would fit in this application.
Maybe even these:

Play field stripped, cleaned and detailed all parts. New rubbers, pop skirts, rod and rings plus coils sleeves throughout.
I didn't like this original post since it made the ball hop really bad. You can see above I changed it to a standard post.
Turned out to be a fun fast little game. A nice example of one of these things for the condition it's in. Was fun to fix up and get working again.
good day.

Shot a vid of my table. You can see it's no slouch now.
good day.

Man....chopperthedog....you sir are an inspiration! :applaud:
Seeing your Fireball gives me hope that I can bring mine back from the "mostly dead" state it's in.
