[Elecraft] KPA100 R 19 R20 question

[Don Wilhelm]

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.
