[R-390] RF Gain control

[dog]

I got the 10 turn pot from China, on ebay. I it was about $6 for 2. They 
seem OK, they're blue. I had to take a round file to open the hole to 
get them in, but the nut covers the extra opening, and it wasn't much, I 
hardly noticed it after I filed it, took about 10 seconds of filing. 
Took about a month to get here. Supposedly 2W, 100Ω. I think they're 
back ordered on Mouser. I think I've got a Centralab number somewhere.
