Most of my noise seems to be coming from the DMD and changes with the light show in attract mode, do any of these fixes apply?

Do the data east boards whate the same overdriven amp circuit as whitestar? There is a mod I read about that I did on my tspp where pots or just resistors are put in line on the mpu and reduce the audio signal which took away 90% of the hum.
