AFAIK, the H7xx power bricks of the 11/34 (among others)
work without any load. At least that is the way I repaired
2 of those up till now.
When the voltage output is present (again), adjust it to
the nominal value (without load).
Expect a small adjustment of the output voltage when the
brick is installed and connected in the PDP-11.
Hint: make a note near the opening from where you adjust
the potentiometer. It saves some sweat on your forehead
when you think "which direction and how much do I turn
the screwdriver?".
success,
- Henk.

One tip. If you have the 'bricks', make
up an extension
cable -- 8 pin
mate-n-lock plug to socket, all pins wired. You
can run the 'bricks'
outside the box then, for short periods with low load
How low of a load can I go with the 11/34 bricks?
(I want to start working on my 11/34 soon! It sounds like I
can still do
this with my very limited electronics knowledge.)
