The board is divided into three sections separated by score lines. The score line at the top in the image will separate off the heater supply. The score line below that will separate off the rail supply and the heater supply. The different sections must be wired together because there are no traces connecting the sections. This also means that the ground planes for the sections must be separately attached to the star ground.
