| Next use a wirewrap tool to connect the pairs of pins indicated in Chart Two. Consider your final placement of the sockets and make your lines long enough to accommodate. With this layout you could place a small amount of non conductive material between the sockets and place them bottom side to bottom side once you have tested the circuit and trimmed the long pins on the sockets. **Remember to take into account that you are turning the socket upside down when you wrap**. Check your pin numbers carefully. Check off the boxes in the first column when you wrap them, check off the third column when you confirm the wiring with a continuity meter. You may find it helpful to use a little double sided tape to hold the sockets down to your work surface while wirewrapping. I will post photos with labels once I make this version of the chorder. | Next use a wirewrap tool to connect the pairs of pins indicated in Chart Two.
