Would you also like the schematics I traced out of the Boschert OL130
SMPSU and a little Boschet 12V linear regulator? They are part of the
Atlantic Research Intervew 3600 that I worked on last year.
I also have the official ICL document for the PERQ 1 power supply
section, which is a Boschert unit. It includes the schematic (most of
it, the -ve resistance board is not included for some reason). I can
try to scan it if there is any interest
Note that many of these units contain 'selected' transistors. That's
one reason for the house numbers. It may well be a 2Nxxxx but one that
has been tested for some parameter. Without knowing what it was tested
for you are going to have 'fun'.

But I should trace the thing out anyway and try
to draw my own schematic, first.
if you do trace it out, I'd like to add it to bitsavers.
there aren't many boschert schematics on the web
