Just a little update. We're going to try and feed all the voltages on the main board of the control (+5V, +15V, -15V, and 24V) with normal switching PSUs and activate the EN signal that the old PSU fed to the control and that should do the trick. Anyway if this works, I'll be working on a LCNC conversion plan as soon as possible just to be ready when something else fails. I'll let you know how this goes!
