Replaced RFCM and recovered comm's. Going into HV, we had two CPS DC Overloads and I was monitoring Klystron KCCU's and KMAI's when we tried the third HV attempt and discovered Klystron in cav. 7 arced and KCCU was only .34a. HV guys raised filaments on the tube to try recovery but it is really slow to recover (.15a in .5 hours). Letting the RF HV guys recover if they can or the cavity will have to be GSET to 0. Bypassing will take a lot longer since jumper is still on and could possibly take zone down .
