In pursuit of the 'no sound' issue, I have also attached a photo of the PCB on the left side of the back of the cabinet which I assume generates the sound. What is the purpose of the rotary control? (Sorry for the poor picture quality.)ģ. Appears it can be set on any number from 1 to 9 (or something like that). There is a numerical rotary control on the left hand side of that PCB. This appears to be an interface PCB to the speakers.

There is a PCB on the upper part of the inside of the door. There are two slide switches near the bottom of the power supply (photo attached) What are the functions of them?Ģ. I have a number of questions I was hoping forum members could help me out with:ġ.

It is now working except there is no sound even though all the speakers are wired.

It was rat infested but I was able to clean it out and repair traces on the reel interface PCB (made a schematic of the reel interface PCB if anyone is interested). I recently acquired a 'Welcome to Fabulous Las Vegas' slot machine (photo attached -I'm not sure if I have attached the photos correctly - let me know if I need to do this in some other manner).
