The 754 -5V/+20V regulator is only used for the core memory subsystem (like an

You can leave it or pull it, it won't matter in your configuration.
I only have time to glance at this now, but if
you said -5, + 20 vdc, isn't
that a H754 ? that sounds like a core regulator. The H745 is for mos. Am I
not awake yet and I missed something?
There's both a 754 (-5V, +20V) and a 745
(+15V) supply in this thing. When I
acquired the machine (which had long since been decommissioned, it was
equipped with 128KW of MOS memory, I assume this is how it had been used so I
hope everything's kosher...
