Title: IGT M+ (PLUS) Sound Problem
Post by: Madddin01 on October 08, 2020, 06:27:00 AM
Dear All,

I live in Germany and have a problem with a 4-reel IGT M + (PLUS) slot machine.The machine doesn't make a tone. Otherwise the slot machine runs without any problems. Does anyone know where I can possibly buy a new CPU motherboard? I would replace this part if it is not too expensive. Perhaps you have other ideas how to solve this problem.


 If you are interested, you can watch a video about this slot machine. The slot machine was rebuilt for advertising purposes and therefore looks different from the completely original machines.

Thank you very much for your support.:thank_you:
Best regards from Germany
Madddin

Have you checked the wires to the speaker for continuity?

When you get a chance, please post a photo inside where the speaker may be?I hope it's just a simple fix.
The glass and strips are custom made for sure but the game and payouts are a clone of another.M+ machines are rare....made in the early 80's.Is there an identification stamp on the side labeled?It would be cool to see when that one was manufactured!  :cool_thumb_up:

I have made already some photos of this machine which I have safed on my computer. Therefore I am able to post already now the photo of the identification stamp. The photo of the inside where the speaker is located will follow during the weekend.  :wave:

hmm...that tag is showing that it was made in 1988....it's not as old as I thought.
Can you show me a picture of the guts inside?
Especially the MPU board.
I did not know that they made the M+ during that year?
I learn something new all the time.

Did you ever get your sound problem fixed?  I haven't seen a later M+ machine like that before.  That was probably one of the last of the M slots before they migrated to the S+.  Your MPU board looks similar to an S+ and much different than a non plus M slot.

Is that capacitor to the left of the volume control bulging? I don't know crap about that machine but that's what I would suspect if it's bulging.
