I have a TFTC and it does not have a hum. So I would argue this is not "normal data east noise". I liked your suggestion of a band-aid: 200hz high pass cap - this should eliminate it from the backbox but not the cabinet. Very cheap and easy to test.

Do you have your wiring for speakers wrapped in ferrite core?

Quoted from Crash:

I have this issue pretty bad on a Jurassic Park, I think it's the worst of any Data East game I've ever heard. We will try floating the sound board with nylon washers. But wouldn't you also need nylon screws since metal screws will still maintain a path to ground?

The nylon washers on both sides prevent the screws from touching the ground pads on the sound board. Could be verified with a dmm once in place though.
