Although called a concert organ, the style is of a well appointed spinet with 2 full-range manuals and a wide variety of stops, vibrato and expression pedal. The model has two manual 60 note keyboards and a 25 note two-octave pedalboard, radiated and concave to allow both feet to play in heel-and-toe fashion. The in-board speaker was a Goodmans Audiom 60 bass unit, and the amplifier is a KT66 push-pull low distortion configuration. The frame is made almost entirely from solid English Oak. Sixty 12AX7’s are used to generate notes. The original catalogue price of 535 guineas was a serious amount of money!
At least one unit has survived in Australia and is now restored. The pictures of it below are courtesy of Tim Robbins, who also has restored the service manual, which is available for viewing on Tim's website at:
