Question
I have one of these and want to know if the payout can be increased or adjusted. Using it for family and friends to have fun on and not profit.I opened the back and 1 of the large ratched wheels says 80%.I assume this is for the house and not the payout.Also can parts be found for these,my 5cent rejects alot of good nickles. Looked like the coin/slug parts are worn.
Bill:
The Challenger has a mechanical style mechanism in it and it is not trivial to make it looser.
The 80% number you are seeing states the machine was set to return 80% of the coins back to the user (in the long term). This means the house was set to get 20%. So, on average, for every $100 that was put into the machine, $20 would go to the cash box.

Expertise
My expertise is in the area of antique slot machines. Specifically pre 1940 era machines. I have an extensive price history list of slot machines that have been sold on eBay and other auction houses (e.g., Victoria Casino Auctions, Rich Penn Auctions, etc.). PLEASE, do not send questions about anything that is not coin-op related. I have no expertise in other items and cannot help you.
Experience
1. I run a discussion forum on coin operated devices (http://www.coinopcollectorforum.com)
2. I maintain a web site which tracks price trends for antique slot machines (www.AntiqueSlotMachinePriceGuide.com)
3. I published an 8 hour video tape on how to properly restore a Mills slot machine back in the 1990s
4. I published a book (Coin Op On CD) which was distibuted on a CD. This CD had many articles and thousands of photos of antique coin operated devices. It also had many videos of rare and unusual coin operated devices.
This CD has since been published on the web (http://www.ibuyoldslots.com/COCD/)
5. I have written articles on how to identify fake/reproduction slot machines.
