There are no guarantees, because Avometers always like to
throw curve Balls, but I think you will probably find that your
Model 8sx is actually based on a Mk II design.

You have the Military version of the Model 8sx which you can
tell my the Nato Stock Number engraved along the top of the
Panel. 6625-99-943-1532.

The Military Meters more often than not, kept to slightly older
designs until new versions were fully tested and certified for use
in the field.

The burnt out resister appears to be R7, which on the Mk II
is 980 Ohms. The Mk III is indeed 9.2 K.

I have just looked inside a Military Model 8sx I have here and the
Resistor in question is a Pan-climatic 973 Ohm.

The meter here, is dated May 1964, but without your Serial Number,
we can't be sure if there are significant age related design differences
though.

I can't explain why the resistor is actually 973 Ohms. I have no idea if
the Military Meters were adjusted to a tighter spec, but that value is
clearly marked on the meter I have here.
Sadly, my Camera can't focus in good enough for a useful Photo.
