I picked up a Pentax (analog) zone VI modded spotmeter in a trade.
Appearance is fine, but the meter is considerably off and is not linear from what I can tell. I also have a Zone VI Soligar that's nuts on.
I've been looking for a service manual to see if I can calibrate the pentax to match the Soligar. The Soligar went to RR for calibration and is remarkable accurate.
Any ideas,
bob
Send the Pentax to Mr. Ritter for calibration. That would be my idea.
You may already know about these guys but in case you don't and you can't find what you need to do this yourself, give Quality Metric a call and see what they can do for you (323) 467-2265.
I doubt there is anyone out there that is any better at meter repair and they are sure to have seen that model and it's modifications before.

Richard Ritter did the original zone VI modifications to the Pentax Spotmeter. He can modify and/or repair your meters.
