The assembly manual is wrong, I notified Elecraft a few days ago of the same issue. You should fnd there are enough smaller screws to not run short when you use them for the Z bracket to heatsink assembly.
73 Dave, G4AON KPA500 #573 -------------------------------- "I Just started assembling my KPA500 serial number 0585 this evening. All was going OK until I got to the point where I mount the Z-bracket to the PA/LPF heat sink. The book sez to use 4-40 5/16" black flat head screws. Using this size screw does NOT pull the Z-bracket tight against the heat sink. I've measured these screws three times and I am certain I'm using 5/16" screws. If I use a 3/16" screw, it works fine." ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
