Power Supply Problem

This is in response to Christian Fant's 10/7 response to the earlier question
which I do not have.

I don't have schematic for the HP23-B but do have schematics for HP23-A and
HP23-C.

Circuitry for the 350/275v and 820v outputs appear to be the same for both
A and
C so maybe?? also the same for B.

In the HP23-A manual the ripple specification for both of these circuits is
Less than .05% at 150 MA.

I do note Rus <rlanders at HGO.net> indicates he has a manual for the HP23.
Maybe
its for the "B" model.

My HW101 and its power supply went to a new home long ago.  Wish I still
had it.
