11/34 PSU (Was: RK07 repairable?)

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.
