[Elecraft] Any unused KAF2's out there?

Last night I discovered I may need a KAF2 and am
wondering if any of you KDSP2 owners have one sitting
around that you might part with? If so, please reply direct
with condition and what you want for it.
What I noticed was that I could hear IF filter blow-by
from W1AW's S9+20/30 signal on 1817.5 when I was 2.5 kHz
away using any K2 filter including the 100 Hz. It was not a
spur, but simply the ~2.5 kHz offset carrier leaking through
the IF filter. This is the probably same issue that causes
the K2's IMD performance to degrade for spacings under 5
kHz. The audio filter won't solve the IMD issue but at least
it will make it easier for my ears to tolerate nearby strong
signals.
Again, please reply off-list if you have a KAF2 you
no longer need.
