[Elecraft] KX3 2m external amplifier

[Josh Fiden]

I've been very happy with a vintage RF Concepts 2-417. It's rated for 
170W out with 45W drive. However, I used it very successfully driving it 
from my TH-F6A 5W HT. I never measured the output with that drive, but 
it was clearly considerable. Also, the preamp is quite good. These are 
readily available used, best guess is price around $175-250 for one in 
good condx.
