Thank you again, Don, for these crystal-clear instructions! I got it done, even with shaky hands and numb fingertips. One final question, I use this K2/100 only for CW--which fan setting is best for long PA life? OFF, HI/LO, or ON? Thanks again!

Remove the 2 black screws just to the rear of the front panel, Then the 2 screws on the upper part of the rear panel. There is one screw on each side panel near the top center. Now you should be able to remove the KPA100 from the base K2. Place it "upside down" on a box or book(s) placed just to the right of the base4 K2 (it should be about 1/2 the height of the K2). If you are careful, you can do it without removing the cables. You will need to remove the screws holding the KPA100 shield. Slide the shield out from under the soldering lug located near the ANT jack. There are 4 screws holding the PA transistors - you should be able to snug them down about 1/8 of a turn - do not "beef" them down, just make them snug. Reinstall the shield, and put the KPA100 back on the K2 - Make sure all 3 of the cables are still seated properly. Put the 6 black screws back in and you should be good to go. 73, Don W3FPR On 12/27/2022 7:14 AM, eric norris via Elecraft wrote: > Dear K2 Wizards: > I bought a K2 from a friend's (WA6OCP, SK) estate, and had a 100w lid built > into it by Dave, W8FGU) who also gave it a full checkout and realignment. > I've now got well over 10 hours of TX time on it, and according to the manual > the PA screws need to be tightened. > My problem is I can't tell from the manual exactly which screws to remove so > I can pry the heat sink up.
