First, Carlos, it is extremely unlikely that your
cell "failed". F&H used cells made by Gossen,
and these are really high-quality cells and are
quite well sealed. Selenium cells almost only
fail from water leakage. As long as they remain
sealed, they will have a life of more than a century.
Second, you probably have a misaligned or broken
linkage. Selenium cells need a fairly complex
linkage to multiply their electrical output and these linkages can be fragile.
Third, I believe that new cells can still be
supplied for the F meters. At least, the Rollei
Club on Jersey was still hawking them a few years ago.
