[R-390] R-390 (not A) green gear

[Paul H. Anderson]

When I aligned my R-391 I didn't find a need for the green gear (which I
don't have, but would like, too!).  I got the cams aligned with respect to
each other, then install the RF deck without the crystal deck behind it
(so I can still see the alignment of the cams), double check and tweak the
counter and 10 turn stops to match the 2 +000 sweet spot.

The MC doesn't change because of the indent mechanism, and the KC will
only change a little bit if you're careful.  One of the cams turns quickly
with respect to the KC knob, and is easy to see, so it is easy to check
that it is in the right spot.  The slight down side is I had a bit of
trouble getting a balanced overtravel setting (-970 to +035, or
whatever).  I got it less than 5KC off, and quit while I was ahead, since
I don't think it matters much.

All in all, it didn't seem any harder than aligning an R-390A RF deck.
