K1 noise blanker assembly question

[Peter Spotts]

Hi folks,

This may be an trivia question for Super Don. ;-) In the sequence of
Revs to the KBN1 board, does Rev C include Rev Cr, or is Cr its own
board revision? My board is Rev Cr, and toward the end of assembly
there are a couple of capacitors that for Rev C require special
installation. I don't want to misread either the instructions or the
Rev number and muck things up.  

Oh yes, Happy New Year to all Elecrafters, whether on this list server
or not!

With best regards,

Pete

Pete,

Rev Cr should be the same as Rev C.  If you have the two extra
capacitors, install them as indicated in the instructions.  The Rev D
board had thru-holes for those capacitors, but I don't think the Rev D
board was ever released.  I have never seen one.
