Attention!I am very well aware that some people are copying my kits and listing them as their own ideas, insinuating in their listings that their kits are better, that their capacitors are "fresher". Bullshi*!! Many name brand companies are not making axial caps any more and have not for years, mine are custom made and "super fresh", beat that! While the list of parts to repair boards is not proprietary, don't be fooled!!!  Make sure you are getting the correct parts. You will see their listings are a copy and paste of mine with a few words changed, they don't even bother to change the font! Maybe they didn't do their research and some of my parts listed are purposely incorrect!?!?! My kits may include parts not listed. People that simply copy others work are shysters and those who do not understand electronics are going to make mistakes, I already have spotted some. Big Daddy has been making and selling quality kits for 20+ years. Buy from someone that knows what they are doing and whom you can trust, that does his OWN research, and supports the pinball community. 

Williams System 11A-C Sound board capacitor kit for type D-11297 & D-11298 Background Sound and Speech boards & type D-11581 Audio boards.

Electrolytic capacitors dry out over time and are commonly known to have a 20 year life, these games are all now over 30 years old. Values used on factory boards varied and may be different, higher voltage tolerances are an improvement.

Please note some D-11581 boards are not fully populated and noted with an * below, and that D-11298 boards have caps in different locations and not all are used. 

For boards D-11297 & D-11298 (Pinbot, Early F-14 Tomcat and Millionaire)
**Note: Manual calls for C9 being a 10uf cap, but no examined boards have it populated. 

For boards D-11581 (Later F-14 Tomcat, Fire!, Big Guns, Space Station, Cyclone, Banzai Run, Swords of Fury, Taxi, Earthshaker, Black Knight 2000, Transporter the Rescue, Police Force, Elvira and the Party Monsters, Bad Cats, Mousin' Around!, Whirlwind, The Bally Game Show, Pinbot (Some), Pool Sharks, Rollergames, Diner, Radical!, Dr. Dude, Riverboat Gambler, Bugs Bunny's Birthday Ball. Also used in Arch Rivals video game.  

Of note: The Pinbot manual says D-11297 but I believe it's a typo. All Pinbot boards I've looked at have this number covered, but I've found one that says D-11298-549, 549 is the Pinbot game number. If you have a Pinbot showing D-11297-549, I would love to have a picture.
