Just a comment and a question. I take care of our club's repeaters. One of the power supplies failed this weekend. I watched as smoke came out of it. It is 20+ years old. Here is the comment; make sure the fuse on the primary is properly matched, even if you choose to go lighter. (It's not good to work the PS to the max anyway.) It may not be possible to fuse a power supply to protect everything in it, but at least you can protect the transformer. (I realize this thread is talking small for the KX3, but the subject is power supplies.)
Question; Elecraft radios are protected against low voltage, but what about high voltage? I'm wondering if a FUSED Crowbar circuit would be practical. The fuse (if any) on the PS 12V leads is behind the crowbar. It seems to me that a versatle fused crowbar circuit would be good. Has anybody been there and done that? Maybe someone sells one. I'm past the age when I quit keeping up on components and their specs, so I appreciate comments aye or nay.
