Does anyone happen to know for certain the value of the meter movement used
for the Carrier Level meter on the R390A?  Is it a 0-1 milliamps, 0-50
microamps, 0-200 microamps or what?  My R390A, as usual, has no meters, so
I'm trying to build an external rack-mount panel with larger meters for some
type of visual indication.  I already have a large VU meter that works for
the line-level and I have numerous DC meter movements that should work for
the carrier level meter.  I could probably determine the value of the
original meter movement experimentally, but if someone knows exactly what
was used in the original design, I would appreciate the info.
