  • Wire top pin of R7 to top pin of R17 (connects J5 to J6 tip)
  • SW1 goes in cutout at J1
  • SW1 up = DC coupled, down = AC coupled
  • R7 stands up at bottom of R7 and wires to SW1 center
  • 4.7uF cap from SW1 top to SW1 bottom
    • + side of cap to SW1 bottom
    • - side of cap to SW1 top
  • Wire from J5 tip to SW1 bottom
