Well if it were mine I'd open it up and inspect everything between J3 pin 25 and T1.  I would expect to find a well toasted resistor but I don't know the KPA500 well enough to know which one.

I think this is the third report I have seen on this reflector of a KPA500 blown by accidental high power input since I built mine.    You have my sympathy but it validates my philosophy of using proactive rather than reactive protection.

Please let us know what blew so we can learn from your experience.
