K3 - RFC47 - Circuit diagram error

Stewart Baker
Documentation for the  speaker mod says RFC47 is 100uH. However,
the circuit diagram is marked 10uH.

I don't think it's an error. Inspection of the photographs in the
"Elecraft K3 AF Stage Upgrade Instructions" reveals value code
brown-black-black which is 10mH. The marking on the new part appears
to be 101 which I read as 100mH.

So it's just a recent change not reflected in the published schematic.

Well spotted Bob. The documentation always takes time to catch up.
