There is a very decent PDF manual at w140.com/tekwiki/wiki/466.
That would be the one I scanned. I took a lot of care to make sure it's
clear -- if you find any problems, let me know, I still have the
original files and paper manual.

For serious fault finding I print off a few pages, sometimes as two
sheets stuck together, and make a note on these where to find other
schematics and layout pages. It looks like all the lower voltages get
their reference from the +65V that you will find just below the +140V
supply on schematic <11> Power Supply and Distribution. If all of your
lower voltages are off by the same fraction eg all low by 20% it could
just be that the +65V is off spec and everything else is OK. If you
want I can talk you through some of the stages but I am far from being
an expert and you will have to wait until after our holiday!
