Name: Setchell Carlson, Inc.; St.Paul (MN)    (USA)  
Brand:
Doraphone
Abbreviation: setchell
Products: Model types
Summary:

Setchell Carlson, Inc., 2233 University Avenue, St.Paul, Minnesota.
Trade name Doraphone.

Founded: 1930
History:
Mr. Bart Setchell put radio on the road in 1928! He invented the radio vibrator, which made bulky "B" and "C" batteries types unnecessary. He founded the Karadio Corporation to produce and market the first commercial automobile radios. In 1930, he formed the Setchell-Carlson, Inc. company, in Saint Paul, USA, with his Karadio colleague Mr. Don Carlson. Setchell-Carlson built radios and audio amplifiers, as well as the world's first radio intercom and was an important source of radio and electronics equipment for the Armed Forces during World War II. When the company began producing television sets in 1949, it pioneered "Unit-ized" television construction, a design based on small units or modules that greatly simplified both manufacturing and servicing and became an standard industry in the 1970s. Mr. Setchell was also a leader in developing closed circuit television for school systems and started a new company, Transifier, when he retired to Florida in 1966. Holder of over 100 patents, he died in 1995.

setchell-carlson 32 volt model - requesting identification

I recently was given this interesting radio by a relative.  It is a Setchell-Carlson and orginally was powered by 32 volts DC for use in rural areas but has been converted to run on 110 VAC mains power.  The tube compliment is 6A7 37 75 77 78 78 25N6 25N6 25N6 25N6 (10 tubes total).  The transformer on the side of the chassis is part of the 110 VAC power supply and not original, also the front grill cloth has been replaced.  The chassis is stamped with the numbers 9 30185.

Does anyone know what model this radio is or if another company may have made the chassis? 

Thanks!

Dear Andrew
You show a nice console - but with a very unusual tube line up. Are you sure the tubes mentioned were the originals?

The line up would not help finding it, if it is not original.

The chassis has a knob placement which is unusual. Therefore it should be found - perhaps later.
Please don't use the question mark option when you answer - and perhaps put other questions - so that it will stick to the manufacturer - or later to the model.

I would suggest you create a new model for Sechell-Carlson - if you know the original tube line up.
You would call it unknown - and place it to 1938 ??
Please tell the admins that you will upload pictures. You might measure it first to be able to have some dates and to look up the loudspeaker if it is permanent - or electromagnetic dynamic.

This will help your questions once uploaded pictures, perhaps also from the scale only - if possible all with 933 pixels size (JPG-quality-reduction used).

Good luck!

I agree, this is quite an interesting set.  Thanks for the reply and the information.  I'll enter it as a new model and will include all the information and pictures I have. 

I did find out that apparently Setchell-Carlson made their own chassis and did out outsource that work.

Dear Andrew
Thank you, I found the model with its pictures and link now here to the model.
This gives it a better chance that a guest will write via contact form about the model.
It can already be found at the manufacturer page (red link on the top of this) because you posted it the right way ;-)
