Great input. You could be on to something. Exited to hear if you find a solution.

I just got a TFTC with a horrible humming sound from the speakers. I floated the sound board, and that got rid of about 55-60 percent of the noise. I then hooked up an external power ATX power supply from an old computer I had lying around, and that got rid of another 30-35 percent. I would say I have about 10 percent left, but I think that is actually from the amplifiers, and then a really faint hiss that follows the GI. But these last 10 percent is really only noticeable with your ears against the speakers.
Så All in All, i would definitely recommend going the external power supply route. An old ATX PSU works just fine, and has 12V, 5V and -12V as needed by the sound board.
Forgot to mention that when I had my DE Star Wars, floating the sound board didn't make any difference at all. But I never tried the external PSU option on that machine.
Quoted from Ive:I still though have a constant static hiss / 'shhhhhhhh' through the speakers - not noticeable in gameplay of course but I can hear it with the game sat in attract mode.
Any thoughts on that ??
I'm pretty sure that is just the general quality of the amplifiers on the sound board. I'm guessing that would be nearly impossible to get rid of. It's the same thing on my TFTC.
Quoted from russdx:If any one wants this give me a shout will post out if you can cover the £5 shipping
Which country are you from? I could be interested. I am from Denmark myself.
