Werner,
If they all look the same, they are all good. The old inductive
resistors had a light-blue body, the new ones have a red-brown body color.
I have mentioned many times that body color is not a good means of
identifying components, but for KPA100 R19 and R20, it is good for now -
if Elecraft changes the manufacturer of those parts, then the body color
is likely to change, but that has not happened yet with those parts.
You have some spares (but you will not likely need them)
73,
Don W3FPR.

I don’t know answer off hand and would need to do quite a bit of
research to provide you with the correct answer. Having not yet built
my KPA100 the only thing I can tell you is that some years ago one of
Elecraft’s suppliers changed their manufacturing process which caused
the resistors to be inductive. I seem to recall Elecraft offered free
replacements for a while.
That’s about all that I know. Instead of telling you anything
incorrect, I’ll just leave it at that and leave the rest to an expert
like W3FPR in the morning (after his coffee). Until then, you
probably can find an app note about it on Elecraft’s website.
thank you for your answer.
that's what I knew before. What I don't know is if the the inductive resistors
can be visually identified?
I have 3 pairs of R19 and R20, one pair built in, 2 pairs are "spare parts", but
I don't know if they are all from the good lot or not. They look exactly
identical.
