I talked to Bob Hardie about this very situation. He said in no uncertain terms DO NOT USE ALC WITH A K3. This is due to Elecraft's implementation of ALC.
In general, it is a very bad idea to use ALC to set output power with a power amp -- it is a recipe for serious intermod distortion (clicks, splatter, etc). Indeed, this has been true for at least 40 years.

ALC between amp and rig should be used ONLY to protect the amp from problems in the antenna system, including operator switching errors.
