[R-390] missing pages in TM-11-856

[Jacques Fortin]

Hi Mike,
This drive link provide the first copy of the TM 11-856 that Andy Moorer scanned and posted on his site.
I had this .pdf in my R-390 folder since 2009 (created 2007-02-04: see the .pdf properties).
Andy also replaced this copy with a more "compact" one which is 28,074Ko big: a little less definition, but everything is there.
The good thing is that the C1, C2 and C4 are also integrated in the 148,817Ko version.

Hi Jacques, Larry and Dan,

I think this version of TM 11-856 may have the schematics that your looking for.

See attached the google drive link to the very large file-size PDF.

Cheers,
