Stepped back off 100k. Left tuner in manual.

Body: 

-Replaced circulator load in 1L13-6
-Replaced 50 ohm resistor in 1L19-7, but blew again immediately. Hipotted klystron and heard arcing at <10 kV. Tube needs to be replaced.
-Replaced 50 ohm resistor in 1L18-8. Upon attempting to recover, found a number of nonsensical latched faults and no 24 V permissive making it to the CPS. Root cause was eventually traced to a tripped breaker on the MOPS. Resetting it restored expected functionality.
-Tuned and recovered 1L18-4
