[R-390] R-391 updates

[Paul H. Anderson]

I've been slowly working on three writing works in progress.

There have been too many life issues coming up for me to finish them 
quickly, so please bear with me.  Nonetheless, they still may be helpful 
to someone restoring an R-391, especially the autotune.

1) my boatanchors web site - http://www.pdq.com/boatanchors

2) my R-391 restoration article :

and

3) my R-390/R-391 manual, which is a combination of materials from 
TM-5820-357-35, R-390 instruction manual and material from my article, 
located here:
