That which works fine at 100 watts might not work fine at 500. There 
have been several examples of that here in the past.  I suggest checking 
your KPA500 into a decent dummy load (shortest connection possible) 
before assuming it has gone bad.

That being said, if it is indeed the amp I'd look at capacitors first, 
especially any that are used on all of the bands.
