[R-390] Mystery Component

I didn't think of a cap.  It looked more like some of the much older
molded resistors but probably wouldn't be one of those.  It's
difficult to see but I'm pretty sure it connects to Z503.

The BBODs I've seen have been in a shiny casing and the mold seam is a
bit "sharper".  It still could be one, though I don't find a .047uF in
that circuit.  Still wondering...

Thanks,
