After checking this evening, apparently Elecraft doesn't post
schematics of their amplifier. It would be an interesting exercise
comparing notes.
I suggest you contact Elecraft directly.
We broke down two KPA500's during the 2016 CQWW 160 on its PTT line,
probably due to our own failing PTT setup.
E-mailed Elecraft for repair instructions; promptly received all schematics.
Both KPA500's were repaired within days and are successfully used in
other contest already.
