-------------------------- The K2 was designed to be modular and to be added to as you see fit. To add modules, there are a few jumpers to cut or remove, in one case a cap to remove (that moves signal across the place where a module would be if you had it installed), etc, and you install the appropriate jacks to accept the new module. For me it was absolutely a non-issue and a no-brainer to add the modules one at a time. That said, there are at least some builders who found it onerous to remove the screws in some places and remove jumpers in others. Some guys developed a set of special plugs that you can put into the sockets for the add-on modules to jumper the proper circuits until you add the module. They call them "rework eliminators". Others here can give you the scoop on them. The biggest value in those I would think would be for troubleshooting to allow you to pull modules and see if a problem goes away, but that's not been an issue for me (no troubleshooting yet on ol' 1289 now going on six years old!). That said, it's an excellent idea to build the basic K2 and do all the testing and alignment, then add the modules one at a time, doing all the tests and checks for each one, one at a time, as you go. That way if you do make a mistake you will find it the moment you add the new module, and you'll know where to look.
