Don, thanks, it's the newest KPA100, just bought/built it about a

Jeff,
Before we give any answer, we need to know the level of the KPA100.
Did you build it from the manual Revision D or the earlier Rev C?
Another way of checking - do you have a toroid at L15 and is RFC10 present?
It is not likely to be a sticking relay problem - that almost never
happens with the KPA100.
