I've rebuilt a number of Cushcraft A3 and A3S antennas over the years. (The "S" just means Stainless Steel hardware). Like a dummy, I once totally disassembled an antenna without marking the traps. Cushcraft marks them with invisible ink (just kidding), so you're on your own if you mix the traps up on an older antenna. Turns out it's not too tough to figure out. Also, those crazy little plastic caps that go on the ends of the traps don't hold up very well, and I've found that 2" heat shrink seems to last a lot longer (and is cheaper to boot!).
I've uploaded a few bits and tips to my site that might help, in case you find yourself trying to identify the traps or rebuild one of these. One is a .pdf from Dale KG5U, one is a .txt file with my tips, and a .jpg pic of a trap with the heat shrink end caps. Hope that helps some of you!!
Go to my website at http://www.WB4IUY.net , mouse over [Workshop]. and select "Schematics Manuals". Scroll down to the Cushcraft section and you'll find it.
