I have to wonder about the rationale of spending anything for that extra
1/2 S-unit.
Over the years I have worked most weak-signal modes, including some EME,
so I understand there are instances where an extra db can make or break
a QSO but I can't imagine that happening often enough on HF to make any
difference at all.
I'd think it would be far better to invest that $1k+ in aluminum and
steel that will positively impact both receiving and transmitting.

Those who already have a KPA500 it might be tempted to buy another KPA500
(kit) to get 1 KW output. This would be a 3 db extra signal strength at a
cost of approx. $4.20 per watt which would be very expensive. The cost of
the combiner would also have to be considered. The combiner with a dummy
load and imbalance trip circuit might be feasible to market at approx. $500.
