[R-390] What's the latest military manual discussing R-390A?

[Roger Ruszkowski]

Andy,

I left the Army Security Agency in 1975.
I knew that  at least 5,000 receivers were still in use
operating 24 x 7 and no end in sight.

I had been training the maintenance manpower to keep them all operating
while an instructor at Ft Devens. in 72 - 73

We did not care what the date was on the TM 11 5820 - 358 - 35
My 61 copy on the shelf is marked superseded in 72.
It may or may not have been. 
It may have just been  marked up to get it out of the building.

We did keep the latest copy of the parts manual (also very marked up with changes) on
the counter at the parts department window.

I just finished scanning a Navy training manual "Radioman 3&2" NAVTRA 
10228-F, 330p, dated 1971. It mostly talks about silicon receivers, like 
the R-1051, but there is a half-page on the R-390A with an image of the 
front panel. Clearly, they thought a radio man in 1971 needed to know 
about these receivers, implying that they thought you might run into 
them in the course of your service.

Anybody know when they printed the last "official" military manual 
mentioning the R-390A as something besides a historical curiosity? I was 
a bit startled to find it in 1971.
