QUESTION: sorry, i forgot the pictures

ANSWER: Hi Steve,
Your jackpot "trip lever" looks fine from what I can see, but if you will notice the top payout slide is still out (forward), if the top slide was retracted the Jackpot trip lever would be allowed to drop, but right now the top slide is stopping it, and holding the jackpot lever up by the top payout slide from being out. I can't see that top spring well enough to see if it is broken or not but if it is, yes this is your problem because this top spring would pull the top horizontal payout lever out from behind the top pay-out slide, allowing the top pay-out slide to retract, with no spring or broken spring on this top horizontal payout lever, the top lever will not have a way to move out of the way of the top slide, allowing the top payout slide to retract. Great photos, very helpful, thank you!

Thank You

Everything worked just like you said it would! I manually set the reels to tic tac toe and the jackpot instantly released. The sliders where were you said they would be.
big question: how often should  tic tac toe jackpot hit?
does it have to do with the amount of coins in the jackpot?
that top spring did not just fall off and it wasn't broken either.
I believe this is another case of an unscrupulous owner.
Don't forget to send me a description and price for the repair manual.
I might also be interested in a back door lock, the one on it is a mills and it rattles just a bit, I could live with it.
Thanks again,

Hi Steve,

How often should tic-tak-toe come up? Well that would be a tough mathematical question and there are ways to figure this out, and there is an out of print book and I have that book, to help figure out the odds on different reel strip combinations and layouts, but it would be a big job and not one that I want to do right now to figure out the odds of hitting that combination, to even do this first off we would have to know every symbol on each reel and the layout. But I know you're not asking for that so let's continue. I would think it would hit once in a while as that is an 18 coin payout, much like any 3 bells, and that will happen, but not without some play. Like, maybe one in a hundred plays or so at a guess.
The Jennings original Yale back door locks for these Jennings machines are not cheap, originals going for 70 to 140 on ebay when they show up. Some Jennings machines did use a Mills type bell lock on them with the side cut key, I know as I have one just like that. If the back door rattles you should be able to adjust that in some way, or use a rubber stick on pad to tighten the door a little, something can be done here. If you do want that manual or want to know more about it Please write me at: so we don't have to use up allexperts resources to talk about it, and if needed, sending photos or other things. Also Steve; I want to thank you personally for all the fine feedback you have left me here at allexperts,  very kind feedback, and thank you for doing that Steve!
Thank You!

I am an expert on old coin operated machines, slot machines, trade stimulator's, jukeboxes, old arcade machines, etc. I have been identifying these for people who respond to my web site listed below, for a few years now. In almost all cases I am able to tell them about their old coin operated machines, the year, the value, and other general information about their machines. I do not know much about soda vending machines, coin banks, or scales, but I will try to help you with these if I can. Please email photo's to: My web site is at:


I bought my first slot machine, a .50 Cent Mills Black Cherry in 1969 and have been hooked from that time, I still have that Slot machine! Before that I found a open barrel full of old scraped jukebox wall boxes behind a restaurant, I wanted them all but never took a one of them. Anything that took a coin drove me nuts!

C.O.C.A. and other slot and coin operated machine groups, associations, groups, and clubs.

Many, the Coinslot magazine, always juken, Coin Slot Journal, Slot Box Collector, and others that I don’t remember at this time.

Graduated from Ballard High School in 1969, went to Edison Technical Collage for a couple of years taking welding and metal fabrication, tig, mig, heliarc, also arc and gas welding and fabrication. Then Apprenticed under a slot machine technician who worked in the slot machine industry Reno Nevada, and set up bar poker progressive machines in the casino's, and repaired machine and did the repairs on slot machine circuit boards there. He also was involved in the 2 hand dealer's market and bought and sold machines at the casinos auctions for the secondary market, which includes selling used machine overseas. I learned a ton from this man; he always had the correct answers and took the time to teach me the business. My interest and knowledge in other and older coin operated machine is for the most part, self-taught. It's been my passion from back in 1968 and before, my thirst for knowledge about these machines has kept me more interested over the years, and keeps me searching for more information even today. I have meet and talked to book authors on these machines, attended hundreds of coin operated shows and auctions, and I stay with that to this very day.

Awards and Honors
Take a look at my allexperts rating, and my guest book, links to these are at Also you can check my 100 percent rating on ebay, as I have been there with ebay from their day one, I am user coinslots at ebay. My other awards come from the very people that I deal with, I always make them happy, no matter what it takes, but they always are happy anyway as the countless thank you letters testify to me, so I know I am doing right, and the best I can. I have found so many hard to find parts for people, I hunt them down and don't stop until I find what is needed to get that customers machine running again and back to life, that is my main goal.
