Bill,
Yes, while you are monkeying around in there - removing the board from the
heat sink and all, you may want to change C80 and C81. It may not really be
necessary, because as I understand it, the problem only shows up if the 4700
pf caps are on the low end of their tolerance range. Elecraft is likely
seeing the problem at this time because of one particular batch of caps
obtained, but there is no harm in changing them 'just to be safe'. That
should not be taken to mean that I am advocating changing them in a working
KPA100 - just saying that while doing other work on it - why not change the
caps.
73,
