Linhof rangefinder adjustment
The ground glass has a bit of depth of field, even with a loup while the rf does not. I would believe the GG with a loup and careful measurement. The rangefinder adjustment screw of the 6X9 is--get this--behind the leatherette beside the front rangefinder window. Adjustment will mean carefully prying the leatherette up and regluing afterwards (once you have the leatherette up you will need to pry up a thin metal cover that is glued over the adjustment hole).
Before doing this check your distance at infinity, 15, and 3. On 15 and 3 check with a tape measure.
The entire RF/VF can be disassembled and cleaned (I had a Biogon version), but unless you have worked on these devices before I would only go so far as adjusting the screw under the leatherette. Otherwise, send it out for repair.
Hope this helps,
