Further to the model notes, the case is veneered particleboard with particular attention to finishing the exposed edges. The front is aluminium and perspex (or similar) with provision for some inputs. The speaker and aerial connections are on the rear together with the pickup connections and selector switch. There is a DIN connector, presumably for a line level connection.

The circuitry is mainly contained on three separate circuit boards, one for the RF stages, one for the pickup equalisation and third for the stereo output stages. The four output transistors are on a heat-sink separate from the AF circuit board.

The power supply filtration components are also discreetly mounted and some tone control components are mounted on the appropriate rheostats.
