A short in the anode has developed during the heater ramp up. Increasing the current limit did not cure it. Start heater ramp down to investigate.

 Wednesday, July 04, 2012: short found between anode and target. probably caused by the target tube coming in contact with the anode due to bending of the tube caused by heating and deformation of the grid retaining ring. see attachements
