[Elecraft] K3 speaker resonance problem

[Allan Taylor]

After a rather hectic month, I finally got my K3 on the air this
afternoon. (Worked by coincidence another K3: WA7VHO)).
But unfortunately my unit (from the kit) has a speaker resonance with
the cabinet at about 700 Hz or so. (Not good for a CW
op!)  As others may have had this problem, could they share the
likeliest screws to fuss with or case components to reposition
slightly?
