Tom, They are listed at the bottom of the Elecraft website. I put them in my K2, and they are great. What they are is a board that plugs in to the connectors for the various option modules, KSB2, KNB2, KAF2, etc. By following the instructions with the eliminators, you will install the various components and jumpers required to make The option work. When you are finished, all you need to do to install an option is simply unplug the option header board and plug In the module you just finished. No disassembly of the K2 is required, as all modules plug in to the top of the boards. You can do them as you assemble the K2, or go back after it is finished and install them. They are great for troubleshooting, since all you need to do is unplug the suspect module and verify operation. I had an issue with my KSB2 board, and it was great to be able to simply unplug it. If you do not have the rework eliminators installed you must solder in jumpers, and other steps to remove a module.
