- Design by Eden Minns. Double conversion on SW, single on MW and LW. On shortwave signal is fed through special coils and tuning condenser into mediumwave section. Bandspread tuning. The shortwave range was selected by using a special sw-dial to the right of the mw/lw scale, fine tuning by using the mw/lw dial. SW-range 13.9-50 m. Variable selectivity in four stages, giving audio range of 8500, 7000, 4500 and 3000 cps. AFC (Murphy: Automatic tuning correction, ATC) and noise suppression automatically switched on in both high qualitiy positions. On high selectivity positions ATC and N/S could be switched on optionally via a switch on the back. A clutch switch on tuning condenser closing and cutting out ATC while tuning control is used. Alphabetical tuning. Cathode ray tuning indicator. Record changer Garrard RD1A with piezo-electric pickup. Handles up to eight mixed ten or 12 in. records. Two loudspeakers differ in size. They are specially developed for this model, built into special sound chamber. Walls are dampened by 1.5 in of felt. Arrangement should restrict the outlet of sound to an aerea similar to that of the combined aereas of the diaphragms of both loudspeakers. The two loudspeakers were intended to give spartial -"steroscopic" - effect, according to the manufacturer and one contemporary test report. Two chassis used, power chassis at the base of the cabinet. This set is very rare today, it is considerd to give an even better performance than the A40C. Cabinet of Bombay rosewood and Bubinga. Inside of top lid lined with grey felt. Power consumption 200/220watts Price when new £85.
