That is a very good argument for having ALC active between the amp and
radio. It would have likely saved the amp.

Well if it were mine I'd open it up and inspect everything between J3 pin 25

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.
