[GreenKeys] M31 / AN/AGA-1 (was Newly-discovered resource)

[Duncan Brown]

Ed,

I have been looking for information on the AN/AGA-1 control/TU box for 
5-10 years.  Have never seen one and rarely seen any mention of it.  The 
military nomenclature for it was TT-31/AGA-1.  I will send you a one 
page military AN/AGA-1 description I found on the Internet (and to 
anyone else interested).  This description is dated 1958 and is a little 
different from the Tele-Tech article in that it uses octal tubes and the 
tones are 2275/2475 cps.

The Feb 1947 Tele-Tech article was probably written about an early 
version, as the M31 manual (Bulletin 200) is dated Sep. 1947 and the 
military cover sheet is dated Oct 1952.
