Hi all,
Game plays fine, but there is annoying noise in the audio in sync with changes on the HV score screens.
Any idea as to where to look? I assume I need to recap something.
Best,
Mike

Same problem. Unable to root cause.
Suspect it may be inherent to the design.
Looking for advice from others as well.
I currently have two Supersonic machines. One has the issue and one does not. I believe this is noise coming across the ground signal for the game.
Both machines have the sound card isolated from the backbox mount with nylon washers and nylon screws.
The game that doesn't have the noise issue is using a Stern solenoid driver board. Both solenoid driver boards were rebuilt by me with recommended mods.
The only other thing I can note that is different, is I did all the repinning in the quiet machine vs someone doing most of it in the noisy machine.
I have not had time to swap parts around. I may not either since I have a potential buyer for the quiet machine.
