I bought the MODE 7 MKII in kit form - Circuit Boards and Construction + Fitting Manual. Below are photographs of the circuit boards, top, under side and fully constructed boards. I have included a Circuit Diagram although I cannot guarantee their accuracy as they are reversed engineered from the circuit board.
