Need help identifying source of a sound in my pachislo. I purchased my first electronic pachislo machine, a Yamasa Neo Planet. Love it, but I live in a condo and the sound is loud. I was able to locate the 4 speakers and unplug them from the motherboard HOWEVER I still hear sound when the wheels turn. It's a loud shrill hum that gets lower every time you press a button to stop the wheel. When all wheels stop, the sound stops. I think it's coming from the wheels themselves???? Not sure. Is there any way to locate what that sound would be and where it's coming from, and then is there a way to lower or modify it?
