[Elecraft] Upgrading Unbuilt K2 #3275

[Freemangw55 at aol.com]

When I purchased K2 #2811 almost two years ago, a lot of intervening  
"happenings" delayed my starting to build it.  I did buy most of  the accessories 
including the KPA100 but excluding DSP, either KAT or the  BATT.  I also bought 
the KPA100 Shield Upgrade and the entire Rev B  Upgrade including the circuit 
boards.  
 
Now, if I get both the MCU 1.09 Upgrade and the K2 Key Mod Kit, will I  be 
able to use Revision F of the K2 Manual to start building?  Or,  have there been 
minor component changes and "tweaks" in the latest  version of the manual 
that did not rise to the level of actual mods.
 
For my curiosity's sake, what happened to K2 Manual Revision E.  It's  not 
available now.  Did
it ever exist? Is there a juicy story behind this question?
 
Tnx,
