This Power Supply Cap Kit will work on Williams System 11B & 11C that use the D-12246 5765-12317-00 Pinball Linear Power supplies used on games such as Taxi, Top Dawg, Jokerz, Earthshaker, Black Knight 2000, Police Force, Shuffle Inn, Transporter, Elvira and the Party Monsters, Bad Cats, Mousin’ Around, Whirlwind, Game Show, Rollergames, Pool Sharks, Diner, Radical, Riverboat Gambler, Bugs Bunny Birthday Ball, Dr. Dude and other pinballs or any other game with this power supply. This “Mega Deluxe Cap Kit” has a total of 7 Capacitors which includes the 18,000uf Axial capacitor and one zip tie to tie it down to the PCB. All capacitors are 105c in this kit. All radial capacitors in this kit are Top quality Nichicon low ESR / high hour rated. I have never seen another vendor kit with all 105c axial capacitors including location C10 (18,000uf 25v) included but this kit does because we had them built special for us to put in the kit. All of our Cap Kits / Get Well Kits include a sticker so you can place it on the PCB to help you keep track of the work you did and when it was done. 7 Capacitors included in kit with great instructions and we include a cap map custom made with photoshop that we created to aide in the installation. We stock most other components that may be needed to repair these power supplies. NOTE: Verify your power supply model because some early 11B games used the D-8345 kit and not this D-12246 kit but we have both on our site if needed.
