[Johnson] Ranger Chirp

[Harry Vaught, KT4AE]

Tried the 6AH6 and 0B2. I resoldered some connections in the area of the 
LV rectifier and improved the ground on the modulator  screen resistor.

I've still got the chirp time on 40 or 80.  It chirps worse on 20 or 15. 
  I suppose that's the multiplier effect exaggerating whatever chirp is 
happening on 40.

This isn't important enough to me to do any of the more intrusive mods, 
I think I'll just be satisfied using this one on AM.

Thanks for the help.
