[R-390] Carrier-level adjustment pot?

[David Wise]

This approach employs the technique programmers
refer to as "brute force and ignorance".  It fixes
the symptom but not the problem.  I discovered a
simple wiring change that makes the original 100-ohm
pot behave.  You don't have to remove the IF deck.
See my 10 Feb 2003 post, archived in the Panel Meters
chapter of Wei-i Li's "Pearls Of Wisdom", at
http://www.r-390a.net, on the References page.

(In May and June of 2006, Gary Gitzen and Pete Williams
expanded this concept to accomodate replacement meters
in the 100-ohm range vs the original 17-ohm units.
Their posts are in the same file.)
