[R-390] BFO multi-turn knob+ Bourns near equivalent

[Cecil Acuff]

While you are at it lets get rid of the rattling mechanical frequency 
display and put a real live digital display in it's space that shows the 
actual frequency one is on by counting the frequency results of the PTO and 
the various conversions.....that shouldn't take more than another 30 or 40 
tubes huh?  We'll call it the R-390B....I guess that would stop the "Non-A" 
description because we would actually have to use the radio's nomenclature 
to communicate which one were talking about...

Cool!

Cecil...
