@jbuhl Don't stress. Focus on good conductors, good connectors and secure connections...
Lots of knowledge from Steve and the other folks. I have used both Viborg and SonarQuest. Both are very good. Even though I prefer silver over pure copper, I have no issues using rhodium based connectors.
Nice Easter sale going on at partsconnexion, so may be a good time to pick up more DIY stuff...
