I just noticed the meter on one of my F2A bodies is not working. I thought it was the 2 MS76 batteries (which had the beginnings of corrosion on them). I swabbed out the battery compartment and cover and put in a new 3 volt lithium battery, but no luck. The meter needle remained absolutely still. The F2A finder worked properly the last time I used it (a couple of months ago), and I know it hasn't been dropped or bumped against something. Can anyone recommend a repairman (other than Sover Wong) to whom I can send it? I really want someone who is expert at servicing the F2A finder. I was going to send it to APS, but the last time I asked them for a quote on a piece of equipment, they seemed high. Thanks for any help.
