[Elecraft] Amp choices for QRP K3?

[WILLIS COOKE]

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.
