[R-390] Dave Curry R-390A Filters

[Steve Hobensack]

Craig, after the filter installation, the small trimmer cap should peak at 
two places in the rotation. If it peaks at only one position, small amounts 
of capacitance will have to be added or removed outboard. If you have a 
midget variable and a capacitance meter, you could find the approximate 
value experimentally.
