double check me before doing anything but if ya open it what you'll probably find on the primary side of thr tranny is 4 connectors... the outside 2 have the power cord attached (with the switch et al..) and the center 2 are jumpered together... if so... then if ya remove the jumperand then wire the 2 sections in paralell ya should have it... ie connections 1-3 are one side and 2-4 are the other... is that right??? i may need more coffee... or is that backwards??? if ya try it unhook the power supply from the unit till ya get a chance to power up and check the voltages at the regulators...
