Wireless as it should be

How different the average ‘wireless’ set is from its name, wires here, wires there, wires everywhere, but we have just seen something different a set without a single wire visible.

In a very cosy room an Express and Star representative visited was a handsome cabinet, quite a piece of furniture in itself, and in this every thing is concealed. In fact, there was nothing in sight to remind one of wireless. Upon raising the hinged lid there appeared the few operating dials, and a pair of double doors midway exposed the loud speaker, not the ordinary kind, but one in harmony with the cabinet and forming part of it.

A switch marked ‘off’ was turned to a position marked ‘on’ (just as simple as switching an electric light switch) and instantly there came floating through the room sounds of an orchestra, beautifully clear and distinct: every note of the instruments could be heard without distortion or scratch. A few moments later came a deep "Hullo," followed by an announcement in Flemish. It appears that the set had been previously tuned to Brussels, and the little switch only required turning on to again receive that station, no further adjustments being necessary. Inquiries showed that this switch enabled any station to be tuned in, and when again switched on - even after several days - the same station would be immediately received.

A slight alteration to the dials brought in London, Manchester, Bournemouth, and several other stations, and in order to further show how easy it was to get foreign stations, Paris and Brussels were tuned in in less than five seconds each. This set is specially designed for those who know nothing about wireless, and yet wish to enjoy the excellent concerts now being broadcast: and in this respect it will particularly appeal to ladies, not only on account of its simplicity, but for elegant design and purity of tone. The sets can be supplied to harmonise with existing furniture - mahogany, light or dark oak, etc.

It is a pleasure to add that it is the product of local labour throughout, and we feel sure that when this A.J.S. set is heard in the demonstration room of Mr. Gordon Smith, the sole district agent, Lichfield St., Wolverhampton, any doubts there may be regarding one's capabilities of  ‘managing’ a set will be instantly, removed.

Five new models were introduced in 1924, with an overall price reduction. The receivers were all T.R.F's and a voltmeter was included in each model to monitor the accumulator voltage. An optional coil unit was also available for other wavebands.

Type 'D'
A simple 2 Valve T.R.F. receiver, consisting of a tuned high frequency amplifier and a detector. This was the simplest A.J.S. receiver so far, costing only £17.10s.od. It was only capable of driving headphones, and was available in a walnut or mahogany case, with a sloping front panel.

An A.J.S. type 'E' receiver.

Type 'E'
This was a 3 valve T.R.F. receiver, consisting of a tuned high frequency amplifier, detector and audio amplifier.

It was available in a walnut or mahogany case, with a sloping front panel, and sold for £22.5s.0d. This model was capable of driving a loudspeaker, which was available for an extra £4.15s.0d.

Type 'F'
This receiver was a 4 valve T.R.F., and consisted of a tuned high frequency amplifier, detector, and a two stage audio amplifier that was capable of producing reasonably loud sound. Three versions were available in different cabinets:
The type 'F' sloping panel receiver

The cheapest model was in a sloping panel case, in walnut or mahogany, costing £27.5s.0d. The valves were externally mounted, and in the centre at the top was the accumulator voltmeter.

This model was in a table top case, in walnut or mahogany, with a lid to enclose the valves and controls. It sold for £31.10s.od.

We would like to thank John of J. G. Communications for kindly allowing us to photograph his type 'F' receiver.

The type 'F' pedestal receiver

The top of the range model was housed in a free standing pedestal case in oak or mahogany. The case included a built-in metal horn loudspeaker, and battery compartment. The receiver sold for £52.10s.0d.

The A.J.S. standard horn loudspeaker

The loudspeaker was 24 inches tall and had a grained wood finish. It sold for £4.5s.0d.
