[Elecraft] K2 PLL upgrade question

[wil.zeebregts@xs4all.nl]

Hi all,

Today I received my K2 with s/n 3967 from QRPproject, Berlin, Germany.
When I browsed through the box I noticed that I received the K2 PLL
upgrade instructions, rev. B, April 25, 2003, and an enveloppe with the
code E850146.

To me, this is somewhat confusing because on the website of Elecraft there
is an announcement of the PLL upgrade, rev. C with the same date (April
25, 2003) and a kit with the ordercode E850138. 

My kit instructions have a lower revision number (B instead of C) but the
kit has a higher codenumber. On the website and in the mailreflector I
can't find anything regarding E850146. Should I use the E850146 kit, when
I am near page 47 of the manual (which could take a while), or should I
obtain kit E850138?
