I've just completed assembly and testing of my new KX1 and KX1AT.
I built s/n 1287 in 2005 and later traded it, with some regrets.

I have a few comments concerning the assembly instructions.
(Page number references given are from the Rev. E Manual, dated May 21,
2010)

Page 42, installation of R32:  I was confused a little by the sentence:
"This resistor is not present on the Revision B or B1 PC boards."
(I wasn't sure whether to install R32 or not, since I had a Rev B board.)

I think what the writer meant was: "A space for this resistor was not
provided in
the layout of the Rev. B or B1 PC boards."  That's what I assumed, so I
installed the resistor.


Page 53, Installing the standoff for Q6 collector:
I ended up omitting the split washer at the bottom of the board, as the
3/16" pan head screw
was not long enough to engage the threads of the standoff otherwise.

Page 54, securing the board to the top cover:

The step just says to use three 4-40 x 1/4 flat-head screws.  Yet, if Q6
has a metal tab,
a nylon screw must be used for the middle screw.  It would be a good
idea to make this
explicit in this step.

My new KX1 is working fine, and I'll be taking some time to re-acquaint
myself with
it before adding the KXB3080 module.
