The Xantrex 10V 600 A power supply for the TBHT has been moved to ITE to replace the failed TGHT power supply

 A spare EMI-EMS 10 V - 500 A power supply was installed last Friday by John Chow. Dave Morris has connected the controls today and updated EPICS. The local voltage readback on the power supply does not work.
