    For the first time, there was displayed the Radiola Super, probably the most efficient and in appearance, the most pleasing set yet manufactured in Australia.

    The Radiola Super is a 6-valve receiver, incorporating the latest and most advanced ideas in receiver design since the invention of wireless. It is entirely self-contained and operates without any external aerial or earth. It represents a veritable triumph of radio research and engineering and meets every requirement of Australian broadcasting. By means of an entirely new invention, it provides in a superlative degree super-sensitivity, super-selectivity, reception, and reproduction.

    In selectivity, the Radiola Super reaches the theoretical limits of science. It may be used in close proximity to powerful broadcast stations, and yet it will easily tune them out in favor of the more distant stations. It is beyond comparison with any existing receivers, and in general comes very close to being the ultimate in broadcast reception.

    The Radiola Super is featured in three models. the Table type, the Sheraton Cabinet model, and the Sports model all of which are manufactured at the radio electric works of Amalgamated Wireless (A/sia) Limited

    In tuning, two controls or “station selectors” are employed. Each of these is vernier controlled, and cardboard discs are provided, which are clamped in place over the tuning dials. As each station is first tuned in, a mark is made on the disc where the pointer comes to rest, and the station’s call letters are then written in at that point. In tuning a Super, the various stations are picked up at exactly the same spot each time, therefore any inexperienced person is able to operate the Radiola Super with ease and facility.

    The cabinet container for the table model is constructed of beautifully finished mahogany, with a leather handle on the top for carrying from place to place. Since there are no external connections, the instrument can be moved from one portion of the house to another with little trouble. The mechanism lies behind the control panel, and ample space is provided in the two end compartments to accommodate the batteries. The loop aerial is concealed in the cabinet.

    The Radiola is non-radiating, and will not interfere with any other receiving set, however close it may be.

    The “volume control” knob is a new feature; in that it permits regulation of volume without retuning. Except for the loudspeaker, the set is entirely self-contained. Dry cells can be used satisfactorily and are supplied with the set as standard equipment. Should it be desired to use accumulators, sufficient room is provided in the cabinet for the housing of same.

    Portable Description

    For those who desire to take a receiver away with them in a car or a yacht, the portable Radiola Super should make a special appeal.

    It is divided into two units, one the receiver proper and the other the battery cabinet. By means of a special swivel arrangement the upper cabinet revolves on the lower one, and by this means the necessary directional effect is obtained.

    The covering is of black leather and will stand a fair amount of rough usage in traveling.
