Filament voltage was jumping from 7 to 8.1 V and KCCU dropping to 0 at the same time as the filament foltage jumps. The shape of the KCCU curve suggests a dying klystron over a filament board or instrumentation issue. Bypassed cavity to stop unnecessary HV drops.

This cavity is already GSET 0 so we are going ahead and bypassing it so it won't interfere further.
