[R-390] Newbie Question on Docs

[Curt Nixon]

GM All:

I'm new to list and a new owner of R-390A ser 3981, Collins.

I am getting acquainted with documentation and have a copy of TM-11-856A 
(1/56).  This appears to be pretty complete service docs for my receiver 
but I also see reference to Navy Docs and also TM 1152 which looks like 
maybe just an operators manual.

What do I really need to get started?

BTW have the Y2K guide also.

Thanks
