[Elecraft] problem with new KSB2 adapter

[R Thompson]

    I think that there is information missing on the assemble and
operating instructions manual that came with my KSB2 adapter.  After
completing the assembly, installing, and aligning it as per the manual,
it doesn't transmit on SSB.  The differences between the manual and
board are related to U3, with was changed from a through hole SSM 2165
to a SMT SSM2166.  When finished, as per the manual, several component
locations were not filled in, and there were parts left over that were
not listed on the parts list or mentioned in the assembly instructions.

   Blank spots on the board include R20 through R24, C50, and C51.
There is microphone audio up to the input pin (7), but nothing out of
the buffer output pin (5).

   I suspect, seeing as I have spare parts left over and apparently
places to install them, that I'm missing information.  Unfortunately I
wasn't able to find more information on the website.

   Anyone have the information I'm missing?
