Ed, I would suggest following the instructions in the K2 manual. There is a page near the end of construction which indicates a very good time to install the headers for the options. For the list of options that you have, it would be beneficial to install the AUX RF header and the header for

Joe, Cutting the tip off the stem bumper is not drastic at all, and is exactly what is called for in the instructions. See the first step on page 60 of the K2 manual in the right column. With the stem bumper cut, you can then press down on the resistor body to tighten the fastenings for L33.

Hi all, Slowly but surely K2 #6773 is coming together. I've noticed that the stem bumper included for the L33 toroid actually protrudes through the middle a small distance. This will elevate R116 above the toroid, which is not what the instructions (page 61, first column, first instruction) s

Sean, U8 is seldom faulty. Check your soldering - refer to the Soldering tutorial on the Builder's resource page at the Elecraft website if you have questions. If suspicious, re-flow the soldering with a hot iron (750 to 800 deg F). The solder should flow out to an almost invisible edge on
