The proposed addition of a note to use only a 3 amp power supply is not really the best way to avoid PCB damage in case of a short. A three amp supply (or most others unless designed to cut off if excessive current is drawn) will supply as much power into a short as it is capable. So if the traces are not "vaporized" they will still cook until power is removed. This will result in raised traces, carbon paths in PCB's and in general either ruining the PCB or making it unreliable. A fast acting fuse is much better. One should always monitor current when applying power for the first time. Elecraft manuals are far better than the usual kit manual. Like the story of the man who used his new ladder to climb to the roof of his barn and in the winter set the ladder on a pile of frozen horse manure. All was fine until the spring thaw and the then soggy manure caused the man to fall and break a leg. He sued because the ladder manufacturer didn't warn him of setting his ladder on a pile of horse manure. Since a large number of first time or inexperience builders have sucessfully built Elecraft kits and help is only an email away, it seems unnecessary to "dumb-up" the instruction manuals.
