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

[Mark Huss]

For the counter, you would have to use NIXIE tubes, of course. 2.6 by 
0.5 inches, 6 digits (100 Hz). About the smallest NIXIE you can buy is 
an IN-17. It is 0.56" wide, so you need at least 3.4" for display width. 
You are going to have to rework the front panel for this. But it would 
be beautiful!
