Quoted from Robo09:Hi.
I have a Gottlieb Tee’d Off pinball game and when I turn the volume on and up, it puts off a humming sound which gets louder as you turn it up. I’m new to this so I don’t know where to start or what to look for. Any help/suggestions would be greatly appreciated.
Thanks

Does it play sound correctly, but has hum in the background as well? If so, then it most likely needs the grounding mods taken care of, and possible cap replacement depending on a variety of factors, including the actual volume of the hum. On a rarer moments, I have seen bad speakers actually cause this, but not too often.
