All that I needed to do was look up what the Icom's expected ALC voltage
was, and have a friend build the little box with the on/off switch and pot
so that I could deliver a voltage with in that range. Since the Henry
requires about 40 watts of drive to deliver 1500 output, I generally adjust
my circuit so that the Icom cannot output more than about 50 watts. With
the pot set, no matter what I do with the controls, my rig can't deliver
more than 50 watts. I allow a little extra drive because the ALC voltage
deviates a bit as the box and radio warm up. The circuit in the box was
very quick and dirty, and it doesn't provide perfect stability. If the
amp's output yexceeds legal limit by a few watts, no would be able to hear
the difference, so it wouldn't bother anyone. The total cost of the little
box and circuit came to about $25, and took my friend about 2 hours to
acquire everything and build it. It works great.

Alan,
Pretty cool! I know Elecraft recommends not even using the ALC with their
amp or, I think any other as well. And once you get it set you can read the
mic gain settings with the hampod so you always know where to go. No amp
here so I don't have to worry about it yet but that box does sound pretty
slick.
