A.J.S. Components
|
|
|
In the 1920's there were large numbers of radio
kits on the market. These were popular as they were a lot cheaper than
the ready built receivers, and attracted a lot of interest. Many
enthusiasts built their own receivers, and magazines featured designs
that anyone could build from the readily available bits and pieces. To
cater for this rapidly growing market, A.J.S. sold many components
separately. All of them carried the A.J.S. name, but its doubtful if
many of them were produced in Wolverhampton.
