My K3 is #4113 factory assembled and delivered in April 2010. I'm pretty sure the bottom cover had never been off when I did the update mods a couple months ago. That's when I asked Elecraft support about it and I assumed it had been added to later #s. I've never had any issues but run mostly CW at either 5 watts or 100 watts. 73, Brian, K0DTJ
