Current plans are to have Bill Merz's group do routine maintenance, upgrades and repairs to the power supply in cooperation with Hall D. They can upgrade boards, upgrade firmware, etc. No need to bring in Danfysik techs.

I have marked up a "Main Schematic" print with my proposed SOE (Sequence Of Events) relays, and the change in the ground fault circuit. I am waiting for Giles Brown to go over the print with me to approve of the modifications.

Mark and folks from Accel are repairing boards, replacing power transistors, etc. Current tests look good.
