Then in that case power supply is not an issue.. I already have a 12VDC supply installed as I put RGB modules in the front of the cabinet to shine colour changing dots on the floor when the machine was on.. simple enough solution.. a 30W 12VDC LED supply taken from the mains input gives you 2.5A to work with.. plenty to run lights and sound

It should work perfectly in your machine BUT ask Daniel how he triggered his boards just to be sure (unless he has already said and I missed it?).
