The Rev B K2 (S/N >3000) design already has these parts (10M and VFO/ALC
modification) incorporated.

When you get near the end of K2 construction, there are directions to
add a few components from the option kits if you intend to use certain
options.  These should be followed.

Note to Wayne and Eric:

Perhaps the KPA100 errata sheet should be revised to point out the
differences if the KPA100 is used with a Rev B K2.  Removing/replacing
the K2 heatsink is something which probably should not be done unless
absolutely necessary.
