I read your article Phil. WELL DONE! I am considering the mod to my ALS-600 and my Dentron Clipperton-L as well. Seems it would work for both. I would be interested in your kits. The etched circuit board seems more elegant than the perfboard. A question! How is the relay SWR on 6 meters. Of course neither amp is designed for six, but I have some SWR from the relay using my K3 on six. (With the Dentron, I have not tried the ALS-600.
