S-Meter repair?
 

I recently overhauled a quite nice RME 45A. All's well with it now,
except for the S-meter... its dead open. Seems that B+ was apparently
routed across it owing to some defective associated components. I did
find another S-meter that works fine but its not quite as vintage. I'm
curious if repair is possible and economically feasible and, if so, whom
might I contact. Thanks much.

Yes, there are analog meter repair centers.

Do you know who originally made the meter?

Yes, the case is marked "Marion Electric Instrument". I recognize the
name.....

Is it possible the meter movement might fit the older
case?

Actually, the "new" meter fits the hole and looks about the same type.
The differences are that the RME has a yellow, logo'd, back-lit scale,
whereas the new meter has a white face. Both have "S" scales. Maybe I
should simply count blessings and press on?

Will the old scale fit into the new meter? If its back
illuminated the lamp would have to fit into the case.

Some meters, particularly the older ones, can be disassembled. In this
case you may be able to swap parts until you have a working one with the
right appearance, and a pile of useless parts that look like they could
be from a meter.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.

S-Meter repair?
 

Yep, good ideas and I'll explore the possibility. If the face will
mount on the new meter, I can probably do without the back-lit feature.
Or...if I'm real clever, and the way is clear, I could drill and
grommet bush a lamp into the case. I was able to trick-bag a
hallicrafters meter that way, so maybe this one too? I'll have a look?

Look at these web pages in how to make custom or reproduction meter faces.
