CANADIAN MARCONI - HOME ENTERTAINMENT - RADIO
Featured here are various vacuum tube home entertainment radios starting from the 1920's. Your webmaster * does not * have any manuals or schematics for any of the devices featured in this section. Manuals and schematics for many Canadian Marconi radios are available free from the Pacific TV web site. Schematics not found at either of the above sites can be purchased from Antique Radio Schematics for a nominal charge, Just Radios is another site providing Canadian Marconi schematics for a small fee. .
In addition, more schematics and technical information about Canadian Marconi radios can be found at this summary listing at the Radiomuseum.org web site. There, you will find a copy of the Canadian Marconi Service Manual Volume 2.
1974 Master Inex publlished by the Radio College of Canada has Marconi
home entertaimnet equipment listed from 1957 to 1974. If you can find the
model of radio that you are looking for, the listing will tell you which
RCC supplement will have the schematic. Click on either the left or right

This extrsact from “The Early Development of Radio in Canada 1901-1930 by Robert Murray” is likley in the context of the mid 1920s era.
"Production of broadcast receivers, which at that time tended to be produced only from about the beginning of July until around Christmas time. Then there was a complete lull and absolute cessation of production from about the beginning of the year through until early Summer. This period, although an idle one from the factory point of view was a very busy one from the design point of view. It was during the early months of the year that the sales people provided the design engineers and the factory with their ideas as to what the market would require and then there were the usual processes of technical design, the preparation of drawings, the preparation of models, certain kinds of field testing and finally an authorization for production. In those days, the quantities manufactured were relatively small and as I recall our output was limited to 50 or 100 sets a day at the peak”. (Unpublished recollections of S.M. Finlayson, CMC President from 1951 to 1964).

RADIO MODELS LISTED NUMERICALLY
Arabic and Roman numeral model designators are sometimes used interchangeably when refereicing the earliest of Canadian Marconi radios.As one goes back in time, information on the oldest Marconi receivers becomes scarcer. It looks like the Sales Department at Marconi began referring to a "Table" model radio as a Mantel radio starting in 1931. They probably wanted to give customers the impression that the radio was small enough that it didn't need a table.
The Marconi brand name of Citation was used for both stereo radio consoles and television sets.

So why were battery operated radios still being produced in the mid 1930s, even after AC operated sets made their appearance around 1930? The answer is simple. An ad from Radio Trade Builder Magazine ,Sept. 1935 indicates that at least 100,000 homes in Northern and Eastern Ontario were still not wired for electricity. So there was still a demand for battery operated sets. Prior to 1930 all sets were battery operated because the AC power supply had yet to be invented. For many receivers, battery purchase was optional, thus giving the listener the opportunity to source their own ( and maybe cheaper) batteries.
Early radios were sold without tubes. Listeners had the option to supply new tubes from any vendor of their choice. This option was offered in an effort to reduce the cost of a radio. Alternately, the user could install used tubes. Recognizing an opportunity to make some profit, unscrupulous individuals would salvage used tubes from radios, clean them up and sell them as brand new. To thwart these dishonest individuals , tube manufacturers started marking tubes with water soluble ink. If an attempt was made to clean the envelope,, the marking would disappear. To view an illegible tube marking, simply blow your hot breath on the tube. Moisture from your breath will condense on the glass and possibly make the marking readable
Many Marconi radios bear the Canadian Electrical Standards Association (CESA) approval sticker on the rear apron of the chassis. CESA began in 1919, initially creating standards for aircraft parts, bridges, building construction, electrical work and wire rope. The first standards issued by CESA were for steel railway bridges in 1920. In 1927, CESA published the Canadian Electrical Code. Enforcing the code called for product testing and in 1933, the Hydro-Electric Power Commission of Ontario became the sole source for testing nationwide. That is why the Ontario Hydro-Electric Power name appears on the sticker. This agreement ended in 1940 when CESA assumed direct responsibility for testing and certifying electrical products intended for sale and installation in Canada. CESA was later renamed to the Canadian Standards Association. (CSA) in 1944. In 2004, the name changed again, to be the CSA Group.
|Here are several versions of approval stickers for Marconi radios. The four digit number refers to a specific model of radio. Click on images to enlarge.|
|Later on, when CESA became CSA, the sticker was revised into this format.|

Changers & Misc
Many of these radios were made in both tabletop and console models hence they would share the same chassis and schematic.
A few Echophone radios are shown in the Table Of Contents in the Canadian Marconi service manual Volume 1 as being made by the Echophone Radio Company of Canada . Per the book "Radios in Canada by Lloyd Swackhammer" , Echophone made radios for the Canadian Marconi Company in Montreal. Specifically, these were the models 40, 50, and 60 . Things can become confusing since the Echophone 40 and 60 models overlap with Canadian Marconi models 40 and 60. Echophone model 50 has no overlap. with Marconi. Echophone was eventually bought out by the Hallicrafters company.
Does anyone know about the Canadian Marconi plant which was located at 110 North Mohawk St., Cohoes NY? ContactLjerry.email@example.com
Does anyone know why Canadian Marconi did not produce radios in the 500 series be it vacuum tube or transistor? Mmodel 588 is known to be a transistor radio.
