Ben,
Repairing the Nikon Ftn is not that difficult. There are two different problems with these prism meters. One is that the ring resistor gets dirty and
causes the needle to be irratic. The second cause is that the Cds cells change
their resistive properties after long periods of time. I have repaired several
Nikon Ftns by cleaning the ring resistor and replacing the Cds cells. The meter then must be recalibrated for the new Cds cells which involves measuring
the resistance of the Cds cells for each stop and matching this with the ring resistor.
The same goes with the other Nikon meter prisms including the T, Tn Ftn, DP-1 and DP-2.
If you want your meter repaired, I would be happy to do it.
Best regards,
Robert Decker
