I have a Stern Simpsons Pinball Party and there is a loud amplifier hum while the game is in attract mode. It's especially bad as the GI and playfield lights flicker. Is there a way to adjust the amplifier gain?

I already have the volume (in the coin door) at 1-2 and the hum is very annoying.

Thanks
 
Mine hums a little bit. My BF hums too. I kind of figured it was normal. ???
 
Seen this pop up a few times. Make sure your boards are screwed down good. Seems to solve a lot of the Noise issues. Grounds it or something.
