[Elecraft] K3 KNOBS

[WILLIS COOKE]

Posts like this are no doubt well intentioned and good advice in general.  For these knobs with built in stress cracks normal care is not adequate.  Use the short handle for leverage, just tighten barely enough that the knob does not slip on the shaft, expect the knob to fail while you are adjusting the knob at some point in the future.  If can keep spare knobs on hand.  Elecraft are taking steps to get us better knobs and I am confident they will succeed soon and do something that is appropriate, but it takes a while to accomplish these design changes.  I am sure they will let us know soon.

But don't assume that those of us who have had failures are ham-fisted klutzes who don't take normal precautions.  That could be the case sometimes, but certainly not the general situation in this case.
