A video is worth 1000 words: http://www.youtube.com/watch?v=jlwoOetHAkU The LM4950 pins have a pitch of 0.38mm. The video guy said his pins were ~0.4mm. His procedure is exactly what Don described above. I've soldered an AD9834 in KD1JV's ATS-3 transceiver pin by pin but those are wider at 0.65mm. Using the above technique is definitely the way to go for very fine pitches. 73, Bill -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Speaker-Amp-sub-side-inop-tp5470661p5471180.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
