[Elecraft] KPA3 Fan Speed

[Brian F. Wruble]

Hi guys:

I am assembling a K3, and I am at the point where I am adding the KPA3
amplifier.

There is a step where you test the fans --- under CONFIG --- going from FN1
to FN2, FN3, FN4 in steps.  The fans are supposed to progressively run
faster.  Mine seem to maintain the same speed (seems fast, but they are
silent.  I almost can't hear them) for all 4 positions.  I cannot tell the
difference.

Anyone know what this is about?

Tnx de Brian W3BW
