Hi Jack, 

if your KPA500 has LPF board rev. D or earlier then You will need to make LPF TR Switch Rework REV5 modification, Elecraft parts kit: E850607. But maybe there is another issue in your case. 

Try to read first then decide. If you want and you have SMD tools then You can try to make this mods first and test if it was the case. If not then you can send to Elecraft service. If you have no SMD tools and experiences then it is better to send it to them now. The people at Elecraft service are great and professional so no worry about. 

It is not complicated just a bit tight on the board and not so much space around the parts to remove the old one. Must be done very carefully. I made this mod on KPA500 for two friends already and in both cases amps worked well after that. 

Hope it helps.
