[R-390] Teleregister Receiver Level Monitor

[jlap1939@yahoo.com]

Friends,

I try this every year or so hoping to find someone who
knows the particulars about my unit. The talk about
transformers reminded me. The only answers I have got
is about Teleregister, and I have never found anything
on the net, but I am pretty bad (!!!) at using the
search engines..

I will put the information as it appears on the nomen.
tag, on the front. The unit has a concealed hinge door
on the front and the components are behind the door,
and on the rear. It has large and heavy duty line
filters and a large low pass filter, as well as
others.
It is VTVM, w/four vacuum tubes doing the work...
All trim is chrome, and the panel is black crackle..
This Nomenclature tag is black w/gold letters,rather
large, as follows:

            Receiver Level Monitor
                   Made for
            Department of Commerce
       Civil Aeronautics Administration
       Type CA 1318 Contract Cca-26540
               Serial NO. 383
        The Teleregister Corporation
               New York, N.Y.

The one normally used control, a volume, has a black
knob w/ dark purple skirt. There is a screwdriver
adjust calibrate through hole in front cover as well.
Input is a reg. phone jack on ft. cover.

It is in my opinion, without any real flaws, for
running any receiver through. I have run the 390 and
SP 600, as well as the NRD 515 and  SB 303 and 313,
and a Hammar. HQ 180..They are wonderful, on the 5
inch PM speaker in the unit..Flawless sound for
speech.
It allows me an excellent speaker sound without the
need for transformers, as it is able to allow for any
input, it would seem...runs the same from the phones
jack, or any of the line set-ups...just slight
differences in volume setting.

The wiring is that old point to point, in PERFECT
line-up, with stress loops at every connection, always
matched to each neighbor...(You have all seen this
wiring I am sure....). The Ft panel height is 7
inches.and it is normal rack mount...

Anyone ever see one, or know anything? How about when
it was built??  

Also, wonder if I should have THE ELEC. CAN FILTERS
rebuilt..And how would I get it done? Is it necessary?
(There are several lg ones..) I don't hear anything
wrong, but don't know what I should be looking for
with electrolytics...

My Regards, and thanks for reading this mess....
