Hi Deni,
I had a bit of resonance at 300 & 310 Hz. There is a screw just below
the speaker grille that holds the chassis stiffener bar to the top
cover. I found that leaving this screw just a tiny bit loose (or
perhaps, not tightening it completely would be a better way of saying
it) completely eliminates all cabinet buzz on my K3.

I've not used the internal speaker until recently on my K3 and now
find I
have annoying cabinet buzz around 450Hz and 600Hz, not so good for CW!
I haven't tried any damping as yet and just wondered if anyone has
managed
to cure this cabinet resonance.
