Thanks Stan! I'm using a180w brick thats reduced to 10v coming out of a TPC unit.
Since the majority of my accessories are rated for 10-12v. I figured going on the lower side might extend the life of any bulbs.
So It would be 10v AC going into the converter set at 9v DC coming out.
Heres photos of the components for reference if it helps( the control board is probably not close enough):
