[R-390] Stuck Meter

[Guido Santacana]

Hi Charles and group,

  The meters are original. At some point I read a post stating that that
some original  meters were radium painted and others not. I have always
treated them as radium painted and will consider this one as such. Better
safe than sorry. in some of my other radios I have worked on the meters
with some luck except in one case where I inadvertedly disconnected one of
those micro wires. One of my former R390s had a loose meter glass that I
was able to carefully glue back in place without meter disassembly using a
bit of cyanoacrylate and something to hold the glass in place from the
outside.

This particular meter probably has some junk in the gap. The pointer looks
free. Only once did I mess with the pivot bearings in a meter. It was that
of the SX28 and it was done with fingers crossed but the problem was fixed.
So, I will prepare for the delicate surgical procedure in accordance with
the greatly appreciated recommendations from all of your and will report
back with results. The line level meter is fine but I never use it. IN 1979
when I got my first repairable R390A from Fair, NOS meters were easy to
come by. Now they are almost unobtaniuum.
