1L18 -5 continues to blow resistors and trip breakers. Klystron and wire harness looked okay when hipotted, and still no smoking gun found. Pulled the jumper on cavity 5 (3.7 MV/m) and brought back the rest of the zone.

1L09-5: Traced filament issues to an open klystron filament. Upon review, this klystron was part of a batch with an acknowledged welding issue, hence the short lifetime. Making preparations this afternoon to replace the klystron tomorrow.
