Preface to Book 7

Prior to 1930 Philips (Australia) imported radios such as the model 2510 into Australia but in 1931 commenced local manufacture of the Philips Model 1203 following an increase in import tariffs.

The cabinet of the 1203 had a magnificent 'piano finish' which featured the most expensive veneers and cabinetry of the day and represented the 'Ultimate in Console Radios'.

The cabinet was made for Philips by the Beale Piano company.

The model 1203 was priced at 24/10/-, but production was soon halted and it wasn't until 1934 that production restarted with the Model A .

In subsequent years Philips grew to become one of Australia's largest electronics manufacturers.

The Historical Radio Society of Australia (HRSA) was founded in 1982 and has a current membership of some 1260 radio enthusiasts Australia wide (2017) with sub-branches in four states under the umbrella of the Victorian branch.

Over the 35 years the club has been operating, much technical information has been gathered as it became available, and thus saved from an otherwise ignominious end!

The early days of radio saw a great deal of technical information, circuits, and schematics published in a plethora of journals, newspapers and books of the day.

Radio was a fascinating concept and the general public were encouraged by such information to get involved by making their own sets.

Catalogues of the necessary parts were published, and over the early years much experimentation by amateurs was achieved by making and then improving the radios of the day.

Surely we all had the intense fun of building our first crystal set, putting up the requisite high aerial, finding a suitable earth connection, then the excitement of twiddling with the cat's whisker and tuning capacitor until the magic of radio was our own joy - marvellous!

Today, some sixty to ninety years later we still get the same joy from restoring our radios, many of which are older than we are.

The catalogues, technical information, manuals and circuit information for those sets are always in great demand and the need is mostly met by the famous AORSM books which were published annually from 1937 to 1955 (with the exception of some second world war years), and they still serve us well; however they were not exhaustive in the selection of circuits published, and consequently there are a great deal of radio sets produced, technical information for which was not published in AORSM books.

The founder of HRSA, Ray Kelly, was not only an incredible resource in his personal knowledge but had collected a very comprehensive library of radio technical information much of which was no longer available in the public realm. He was instrumental in compiling no less than three volumes of radio circuits which were known to be missing from the AORSM books. Later he also compiled several volumes of circuits for radios manufactured from 1956 to 1960 - after the AORSM ceased publishing in 1955.

This year I have pieced together a large amount of technical data which had been collected in the past by the Society but which required identification and collating into concise volumes of much needed technical service information for the thousands of valve operated radio receivers produced over the years; information which had to be digitised, collated, straightened, compiled, indexed and bound. That exercise has resulted in the publication for the HRSA in 2017 eight circuit books of between 300 to 400 pages each of much needed data.
