"... but If there isn't an ATU on board as I recall there was with the earlier prototypes of the bigger Elecraft amps, I wish that there were one with the KPA 500 and I'm disappointed..."
The SPE internal tuner (and even the THP external tuner) can only handle about a 3:1 SWR. A wide-range autotuner needs a much greater range in component values, as well as higher voltage-rated and higher current-rated components than does a limited range tuner. Look inside a LDG-1000 or MFJ-998 and you'll see what I mean. Adding a wide-range tuner capability inside the KPA500 would add considerably to the size, cost and complexity of the KPA500. When it comes to an amplifier, I prefer an external wide-range tuner. Just my opinion.
