I agree with what Elecraft say, Stan, and just follow the excellent
assembly manual. You can't go wrong if you follow the instructions to
the letter. Those so-called 'Rework eliminators' are quite expensive
for what they are but would perhaps be useful for anyone building lots
of K2 kits or do a

Stan,
If you install the rework eliminators, I strongly recommend you do *not*
change the value of C71 nor install D19 and D20 until you are actually
ready to install the real K60XV option.
Those component changes will alter the VFO Range Select in a manner that
cannot be properly tested
What I do is install the option sockets and plug the components and jumpers
that will be removed into the socket. You must be careful, then, that they do
not fall out. This works for all options except the K60XV, which requires
component substitution.

I did not install the rework elimininators and wish I had. I added the KSB2
last year and did not really enjoy the disassembly and reassembly of the K2
that was required. I also had difficulty desoldering the RF board jumpers

I've only built one K2, #5957. I installed the Rework Eliminators as I
went along with the build, and there was no problem doing so.
Subsequently, I installed all the on-board options for the K2. What with
putting sub-assemblies in and taking them out for various reasons, I am
very glad I had

Yes, the rework eliminators are no longer available, but if you have the
options in hand, you can put in the headers and standoffs for those
options. The K2 manual tells you when to do that.

For some time I had been aware of the Rework Eliminator kit from Unpcbs for use
in the K2. At the time I could see no real use for me. However having built my
K2 and used it for some time I felt I wanted to restore it to its original
state to carry out some initial alignment checks and compare
I agree wholeheartedly. I recently had problems with the KSB2 and 160 meter
mods. It was great to be able to do A/B comparisons and troubleshooting simply
by unplugging the offending module and plug in the header PCB.

Do all these extra pcb's, jacks, plugs and add-ons

Another advantage is if you buy an option like KSB or one of the filters and
decide it isn't what you want, just unplug it, install the bypass header,
and sell it.
No disassembly, etc.
