As he's stepped away from the effort, I am retooling it for a 12V switching PSU, which will provide both voltages from a single 12 volt source. It'll have a small time source to generate either 50Hz or 60Hz AC, selectable via jumper/switch. Have not had time to work on it this year, but need to get it off my bench...
