Hi Barry, As you recall, I ran into the same thing when I completed s/n 2512, and that this was reported to the Reflector March 29, 2011. I hope that the Elecraft folks have noted the problem with the standoff.
I also omitted the bottom lockwasher, and worried about the nylon screw bottoming out. (It didn't). I also worried about damaging the nylon screw during soldering, so I used a metal one just during soldering. (My kit contained two nylon screws, and I used a magnet to separate the metal ones). 73, Chuck Guenther KX1 s/n 2512 Barry, K8QI, wrote: "Figure 24 shows the installation of the standoff using 2 split washers, One below and one on top of the board. I am not able to get the threads to catch using the 2 washers. So I only used the one on the top of the board to maintain the correct heigth of the standoff. I am a little concerned that the threads from the 3/16 Pan head and the Nylon 1/4 Flat Head may contact inside the standoff and result in the Power Amplifier Q6 being loose and not making good contact with the Thermal Pad. Did anyone else have this problem? What was your solution? During the solder process for the Power Transistor Q6, the instructions state to "Temporarily secure Q6 with a 4-40 flat head screw....." My question is should I use the nylon flat head or the metal flat head for this solder step. Any possibility of deforming the nylon flat head during the soldering process due to heat transfer? My thought is no, use the nylon. Thought I would ask, since I already have the question above." ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
