Title: Shielded wires on 2203 question Post by: kevilay on January 10, 2010, 11:45:30 PM Hey guys, i got the 2203 kit and have it all build except the 2 shielded wires. From the layout I can see that one of them solders to the preamp tube socket and the other end to the center pin of the preamp pot. At the preamp pot part another wire joins it. The shielded wire is braided on the other side and solid on the inside. Do i just solder the joining wire to the braid? Also when I solder to the pot and to the preamp tube socket do I solder both the braid and the center? Im not to sure how shielded wires work. Hopefully someone could help me quick Id love to give this thing a go!

Then that braided shield (now a wire) goes to ground. So the "two wires" are the center conductor and the braided shiled.
At the tube side you only use the center conductor to its destination. The braided shield gets cut back and Is Not Used. If you have some heat shrink tube, you can make a sanitary/safe off to cover any little bit of braid that might be exposed. The idea is to make sure that the braid does not make any contact at the tube side of your connection. Does that make sense?
