[R-390] 2uF Replacement Cap

Apparently it frequently goes leaky causing improper AGC action when in the
SLOW position.  Some folks have gutted the original cap and "restuffed" it
with a modern one.  I plan to do this if possible.  I got some 2.2uF caps
which should be fine, but I really liked the idea of the "correct" value
being in there.

Good luck with it,
