Sulphur, LA
I am definitely in for one of these devices! Just the other day I tried using nylon screws, pulling boards and floating them, and messing with the speakers and grounds, and I could not get rid of any speaker buzz.

Quoted from Joshjowen:I tried the White North gadget. It barely helped and the machine made a very loud pop through the speakers at boot up with it installed. I do think it's possible I have a faulty one and have been emailing with White North. I have now pulled it and went the ac/DC 12 converter route mentioned elsewhere and the buzz is all but gone... Noticable now only barely in a completely quiet room and this machine had a particularly bad hum before.
Super easy to install... Tapped into 120 after the switch and wired it to the convertor then just ran wires to the soundboard for the DC. I can't recommend this route enough... The hum/buzz is now even less than my Data East machine with a pinsound and that one is pretty quiet.[quoted image]
Woa I must have missed this solution. Where can I find more info on this mod? The White North gadget helped only some, but buzzing is still too audible in my opinion.
Ok did some digging and here is the fix posted 5 years ago. Basically powering the soundboard off of it’s own dedicated power supply, pulling power off the line after the pinball machine’s power switch, and before the transformer.

Quoted from ypurchn:This thread has gotten so big it’s hard to find anything. Would you mind referencing the post for the converter?
You must have missed my post just a little up the page!
