The circuit and components are located on one side of the PTFE fibre-glass board, the other side

being fully metallized, to serve as an earth. Earth connections are made by fixing screws, hollow

rivets and copper straps around the board and under the emitters, to provide a direct contact

between the component side and the ground plane.
