IGT Double diamond S Plus, coin comparison issue!

[David Walz]

I really don't know what I have here, my books are coming in the next week.
What I here is probably junk, however I need to restore, replace, the coin comparison. Since it's in pieces it might be just 💩.

 I need some input please.

More photo's.

It looks to be a cc-16 (small denomination coin - ie quarter).
CC16D is what is typically used in the S+

Can I get parts for a rebuild somewhere?

[jay]

Most of the vendors on the home page can set you up with one. Give them a call and tell them your looking for a cc-16 coin comparitor for an IGT  S+

Real common part. You won’t have any issues finding it.

Look at the photo I've attached below.
I highlighted with yellow boxes, a resistor soldered onto the coin sensitivity potentiometer dial.
Someone definitely tried to mod that circuit board.
I'd look for a new coin comparitor by placing a WTB ad in the Classifieds section of NLG, or contacting an NLG vendor/member.

That's a large coin CC-16. It won't work very well with quarters. Good chance you have large coin optic spacer in the machine so it won't see quarters very well, if at all.

So that would be a cc-33 not a cc-16

If you want to use quarters you will also need to look at the hopper too.
It would have a large wheel for dollar ls vs one designed for quarters.

No hopper I need to pick one up later on.

  everyone, I will toss this one. I am rebuilding the slot machine.

David,
The small circuit board underneath the coin comparitor is called the coin-in optics.
That board is what registers coins as credits back to the MPU.
You need to take it apart and expose the coin "encoder".

The coin "encoder" guide is a plastic piece that directs the coins as they fall thru between the optical light beams called the "ABC" optics.
If the encoder is too large, a quarter can miss one of the beams and coins falling thru get "eaten"....in other words, although being directed into the hopper bowl, they don't count towards crediting the machine.
The correct "encoder" guide is one that has sort of a plastic molded bend, to push the quarter towards the left, so the coin breaks the "B" light beam of the ABC optics.
If that plastic molded guide isn't there, then you have an encoder really made for much larger casino tokens.

I sure would like to find out what the original amount was with this machine. Does the model number have some sort of decoding?

No....they don't have manufacture build labels, like on automobiles.
Whatever decoder guide that's sandwiched in between the coin-in optics and the size of the slot hole on top of the button deck pretty much tells us what denomination the cabinet was originally set up for.

Take the coin-in optics apart and show me a photo of both sides of it.
There WILL be a part No. molded on the plastics.
You need to take the coin-in optics apart anyways...there could be dust balls starting to block up the three optic holes.... those should be cleared of any debris so the optical emitter beams can go thru to be picked up by the receiver optics.

If you have the coin hopper for the machine, place a quarter on the top of the wheel shelf and snap a photo of the coin sitting in between the wheel nibs.
I could tell you what hopper wheel you have.

You might find the denomination on the reel glass.
One of the best things about the S+ is that it can morph into any theme and any denomination.
The key parts are your coin handling for denomination
Then the game kit consisting of glass, reel strips and the two chips (game and reel).

The coin head (metal piece) on the outside of the door limits the size of the coin that can go in.
A nickel head would not allow a quarter to pass and a quarter head. Would not allow a dollar to pass.
If you have some loose change laying about this might give you a clue as to how it was originally setup.

Since you appear to have had a cc-33 my bets would be that it was a $1 denomination.

As Mark indicated the spacer in the optic board will also be a good indicator

I think most S plus back in '91 started out as $1 machines, and the rest of them were quarter machines.  I remember all the casinos in Las Vegas had huge billboards advertising 98% payback on their $1 slots. They were mostly all S or S plus machines.  Most didn't have BV's yet, you had to go up to the cage and get a "rack" of silver dollar size tokens with their name on them.

OK, how do I identify if this was a $1 slot machine? I want this to be as accurate as possible.

[jay]

Try putting a dollar through the coin coin head. If it goes in then that is that is the most likely.
If it was setup for a quarter then the dollar won't go through it.

Secondly the coin in optic board will have a spacer in place. Stayoutofthebunker (Mark) outlined how to take it apart and send him a pic of it.
That spacer is also a good indication if it was setup for dollars or quarters.

Thanks.
The hopper is missing, I am going to be purchasing one during the rebuild of this machine. I will get some photos of the optics ASAP.

It does not really matter what denom or theme was first put on the machine. They are modular and were built to be able to be changed out easily to whatever theme or denom the casino wanted in a very short time.

[Stayouttadabunker]

I agree with you SCM, but if he can find out if the encoder matches the coin head, it will go a long way to knowing what size hopper wheel shelf he'd need to have later?

But yeah, he could shop around for an encoder and coin head to match the hopper wheel shelf too? lol
