IIRC "George" at Light Metrics (or some such) in Hollywood, CA did the work, and calibrated the meter for a reasonable charge. Quick turnaround, too. Sadly, I have heard that he is no longer in business.
Good luck! The meter is wonderful.

Hello,
I saw on the forum that a couple of years ago you wrote something about a problem with an illuminator of a Pentax spotmeter. I have recently bought a Spotmeter V and I have the same issue. Although the light bulb seems to work fine outside the circuit, I have tested it.
Do you happen to know any specifications on this bulb or replacement options? It would be very helpful.
Thank you,
Best Regards,
Christophe (aka reciprocity)
