Hi all,
I?m just starting in on a PDP-11/34 for a friend (happy holidays!) I currently have the
H765 power supply torn down for cleaning, inspection, and testing as a first step.
While I have the transformer out on the bench, I?m wondering about the line interference
supression caps on the ?CAP MOV? board attached to the transformer. These are CDE 220 VAC
.1 MFD, across the line, in parallel with some metal oxide varistors.
Drawing on collective experience here: would I be well advised to go ahead and swap these
out for some modern X2 safety caps while I have the supply apart? Or are these in the ?oh
those are rock solid; I wouldn?t touch em unless they were faulted? category?
cheers!
