1940's Radio - what schematic?
2/5/2009 10:31:37 PMGareth
My wife brought home a free standing antique radio in wooden cabinet. The radio (steel case with 4 tubes) has a label on it, likely from a repair shop C'Art Scott, Radio Service, 1259 Main E 5-1075 but no manufacturers name. The tubes are GE 5Y3G, Philco 6F6G, Westinghouse 6K7G, Westinghouse 6SQ7 and a Marconi 6SA7. Can anyone tell me anything about this radio, manufacturer, schematic etc. I suspect the age to be 30's or 40's but not at all sure.

To help identify the chassis, and hopefully identify a schematic, the photos can be found at http://groups.google.ca/group/vintage-radio-pic/web/pictures

Look under the chassis and see if the name on the capacitors give any clues. A lot of times they will have the manufactures name. Zenith, Grunow, Philco...etc. Were there any numbers at all on the chassis or the cabinet. A picture of the cabinet would also be very helpful.

Agree with David. A photo of your chassis in the cabinet would be a big help in possibly identifying your radio. Noticed that it includes a Marconi tube and your photo link has a .ca tag on it. By any chance did you buy this radio in Canada?

If it is a Canadian radio after 1938 you won't find a corresponding Canadian RCC schematic on this site. American and Canadian brands often used totally different chassis.

Try to post a photo with the chassis in the cabinet


Best regards

I could be wrong but from the the looks of it I'd say there's a ten year difference between the cabinet and chassis. From the looks of your photo I think someone may have slipped a late 30's 40's chassis into an early 30's cabinet and altered the cabinet to do so.

Anyone recognize the cabinet in Gareth's link.

It does look like a 30's Philco cabinet. The knobs sure look wrong, as well the vertical dial. The tube line up seems not of that vintage. Not a bad fake it though. I would put some wood knobs on it.

When I initially saw that chassis, I was thinking of the manufacturers that I had seen using that shade of orange dial scale,

along with it using a distinctive vertical dial arrangement. I then researched several possibilities, but, found none,

With the tube lineup I tend to want to date the chassis as circa 35-40.


With your posting of the cabinet, that tends to reek of being an older vintage cabinet, in inspection of the inside of the cabinet around the dial escutcheon plate, does it suggest any cutting on the cabinet in order to fit in that unit ? Along with any difference in the aging of the wood after being cut as compared to the normal cuts that are on the original cabinetry ?


Also I see the right angle mounting brackets used at the sides of the chassis, your bottom view doesn’t let me see all of the

periphery of the bottom lip, any chance that there were other mounting holes in it for its previous mounting?

Apparently, the far right control is the tone control for the set, but with an attached unused switch section, on its rear. . .BUT. .
just in its near proximity I see an Aerovox paper capacitor of CANADIAN manufacture sourcing, I see that there are others also.


Isn’t that a steel chassis with a very light black wrinkle finish on it ?


My second attempt was to closely observe that distinctive vertical dials, dial cord stringing and compare it to all of Sams

dial cord stringing arrangements , but that also didn’t make a conclusion.

Could make out the part number of the AF output transformer, as well as the IF 2-2 and IF 1-1 transformer numbers and
the SMOOOOOOOKERS in the house. Couldn’t make out any top ID stampings on that Hi i i igh - boy power transformer.

Gareth take a look at this link.

No doubt that chassis was probably installed along time ago. The dial smacks of something that was used in a radio phono unit. It's almost like he remounted the the dial and components on another metal chassis
to compensate to fit the old cabinet. Whoever did it did a decent job and the radio is still presentable the way it is.

Warren,
I have a 90B, which is similar, but not quite so ornate on the frontal panel. The basic structure
(H x W x D)seems appropriate as well. My knobs (original) appear to be wood with a brass insert for the set screw, and shiny metal overlay. The dial escutchen (not the vertical abortion) is also similar.

:I have a Mont Wards late 20s-early 30s trf console that has a vertical tuning dial& escutcheon that looks very similar to the photo of modified radio. Perhaps search for wards-airline trf chassis with same tube layout in Riders? I cant remember the exact model # on my Airline, but the vertical dial scale looks to be the same to me in the side by side photo.
