The circuit and the components are on one side of the epoxy fibre-glass board, the other side is unetched copper to serve as earth. Earth connections
are made by hollow rivets. Additionally copper straps are used under the emitters and at the input and output to provide direct contact between the
copper on the component side and the ground-plane.
