The circuit and components are situated on one side of the epoxy fibre-glass board, the other side being
unetched copper to serve as ground plane. Earth connections are made by fixing screws, copper straps and
hollow rivets under the sources and around the edges to provide a direct contact between the copper on the
component side and the ground plane.
