Bringing an 11/750 power supply back to life

Someone else provided me with a PDF version of the H7104 Power System
TD. I can send it to whoever wants to make it available.

I was supposed to send the guy some of my extra manual for him to scan a
couple years ago, but I got busy with work and forgot and haven't been
able to contact the guy since.

The print sets are already on the web but is there any chance of
scanning
the PSU TD? Yours is the 3rd or 4th VAX-11/750 with potential PSU issues
mentioned here in the last year or so.

Keep away from the machine and you'll be safe :-)

Seriously, think about each step you are taking,
don't do anything unless you think you know what you
are doing and why, keep one hand in a pocket or behind your back,
and (most important I guess) make sure there is someone
nearby who knows what you are up to and what to do if they find
you writhing on the ground.

If you post more details about the symptoms (which, if any, lights
come on, what readings you have already taken etc) I expect you'll
find this list full of useful advice.
