[Elecraft] SSB output overshoot

I think Don's observations sound like the problem I
and a few others have had. See, for example the
symptoms described here:

These two, at least, were due to the KSB2 ALC circuit
having insufficient attenuation range to control the
output of K2/100's which have above-average overall
transmit gain on the lower bands.  The fix involves
adding a resistor and changing another in the KSB2. 
Gary Surrency at Elecraft was able to provide me the
necessary details.

But Mike's problem sounds much less severe.  It might
be a marginal case of this effect, I suppose.
