[R-390] Lazy doco question

[John Lawson]

I find after an hour of plowing through many CDs and files - that I have 
plenty of info on R-390As - and none whatsoever on the -390.

   So I thought I'd ask if I could be pointed at the 'best' download for 
the -390 - perhaps the equivalent of TM 11-856A (which I have a paper copy 
of, ed of Jan 1956)

   Meanwhile it's off to the Cardmatic for all these Tubes....



    Cheers
