[R-390] meters F.S. maybe usable for carrier level, etc.

[Al Parker]

Hi all,
The link to ATC's meters, got me thinking, & looking.  I found I have
several meters the "proper size" physically, and with specs, unlike ATC's.
They don't match spec-wise to the R-390A carrier level meters, but may work
with some help, e.g. changing the 27 ohm res. in the AGC ckt &/or the meter
zero pot as has been suggested b4 (probably won't make it real good),  or
Jan Skirrow's op-amp ckt (should do the job).

    Here's what they are:
  "Meter Mutiscale: DC,  0-1 ma, 0-100mv,  MR15S1D1DCAV" (this is on the
face as well as the box)  the actual scale is unmarked, but has 10
divisions.
Made by Simpson, date packed 9/17/53.  Packed in stout boxes, with foil
packs & dessicant bags.  (preservation method II)

They are in the original, unopened boxes, and incl mounting hardware.
Digipix available tomorrow, 2 or 3, abt 60k .jpg, emailed to requestors, or
may get them on the website.

I'll sell one to a customer, $18 shipping incl. to CONUS.
sold as is, unopened, but for $2 addtl I'll open & check, & gnty not DOA.
If too many takers, I'll do a drawing of some sort, of all responses recd
by 0100Z Fri.
