This isn't in any of the Handbooks I happen to own. I tried looking 
on LDG's web site but found no autotuner without a box. Maybe it is 
a special order item? Does anyone have more info on this?

I am looking for some way to get better SWR on my homebrew amp 
input, and make it more consistent across all bands. It is a 
homebrew cathode driven 4CX1500B and I have no real idea what the 
tube input impedance is. I opearate 99.9% CW so an autotuner might 
be an attractive option *if* I can fit it in the box.
