2L03 & 2L05 scaling complete. 8-cavity 1-hour run completed on zones at scaled ODVH values. 2L03-1 & 2 reduced by -0.5 MV/m for pressure / heat load. 2L05 starting pulse processing under another ATLis now. Will leave task open until we can LEM and see what fudge factor does.

W202B14 has been populated with (22) Trim Card 3. Cards were set to setpoint and cycled. Ch2 appeared to drop comm while cycling but this was resolved with a trim card swap. Cards were then cycled twice with no issues. We will continue to monitor the rack.

All transformers hi-potted good. Also adjusted orientation of diode stack capacitors to be further away from the adjacent mounting plates. 1L07 had one capacitor that was showing the same signs of arcing to the adjacent plate that was identified in 2L03, but not as severe. The diode measured okay, so no other remedial action was taken. Replacing the X1 diode stack can be scheduled as a PM item over the next SAM barring sudden high voltage issues showing up.

Measured output of RFCM and it was good at -7.78 dbm. Tried to bring CRFP to 400w in OLT and when I got to a GLOD of about -1.3v, CRFP went from approx. 200w to below 90w and would drive further. Getting an IC/PTW drawn up to replace suspected 2.5 w amp. We won't know until zone locked up and cables/amp checked. Checking on 2.5w amp availability as I type.
