Summary:

AJS, A.J. Stevens, Wolverhampton
J.Hill: RadioRadio has a different spelling (obviosly in error): AJS, A.J. Stephens, Wolverhampton. Most other sources, e.g.Brown Brs.Catalog 1925, use Stevens.

Main business: Motorcycles. 1931 taken over by Matchless, but brand name AJS maintained.

Founded: 1914
History:
AJS was established in 1914 as a continuation of the Stevens Motor Manufacturing Co. founded in 1899. Since 1856 the Stevens family had a forge. The company was known primarily as a maker of motorcycles and later automobiles. The letters A.J.S. were the initials of the founder, Albert John Stevens. The company was located at Walsall Street in Wolverhampton. In 1923, the brother of Albert Stevens, Harry Stevens, began a new department called AJS Wireless and Scientific Instruments. This branch began producing luxurious radios, loudspeakers and components. Specialty of the company was the choke coil coupler, a unit consisting of a choke coil with a capacitor parallel to the coil, in combination with a grid leak-capacitor and a resistor, that looked like a traditional LF transformer with four terminals (see photo below). This combination could also be incorporated in the place of a transformer.
On July 10, 1925 a fire destroyed a large part of the production facilities of the radio department. The buildings were re-built in a record time of six weeks and on September 10 of that year AJS opened a prestigious showroom in London at Charing Cross 122-124. In 1926 A.J.S. introduced their first superheterodyne, the Symphony Seven. Unfortunately A.J.S. could no longer keep up with the new developments, and the company stopped making radios in 1928. The production of radios was taken over by Symphony Gramophone & Radio Company Limited in 1930.
