The biggest thing is stripping and tinning the leads. I have a De-soldering station that works very well to run the leads into the hole and strip with heat and solder. But you can carefully scrape the enamel off or use a very fine grit sandpaper to strip them and then tin them very well and look for the very thin coat of solder that tinning does. This is probably the most important part of the build. Always double check them before installing with an ohm meter to make sure you really have them tinned and there is no resistance. Once installed and soldered, carefully inspect the joints with a magnify lens to make sure you have a very nice clean joint, if the wire is sticking thru and isn't looking very soldered...it's not and may work now but will fail later. Once this is done, check it again with an ohm meter to make sure everything has continuity.
Just a little patience and double checking and you'll be fine.

It all looks straightforward in the instruction manual. Would welcome encouragement or cautionary advice. 73 Nick G3RWF _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
