Why not have it repaired and calibrated at the same time? An uncalibrated light meter is useless dead weight.
Nobody left to do it. The place everyone recommended in California is no longer doing it. There's a place in the UK that says they'll do it, but I'd have to mail it both ways and they charge like $180 or something far exceeding the value of the meter. More than I want to spend on a curiosity.
The good news is the meter has a user-accessible adjustment for calibrating it. Whether it's enough to get the meter to a useful place, we'll see if I even manage to get it working at all. I have a spot meter as well as several in-camera meters that I trust, so I should be able to get a good comparison and find out for sure if the meter is trustworthy when all is said and done.
