Summary: |
Setchell Carlson, Inc., 2233 University Avenue, St.Paul, Minnesota. |
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.
Transifier was a MATV (master antenna TV) company located in West Palm Beach, Florida. They manufactured mast mounted MOSFET VHF/UHF TV preamps, UHF notch filters, audio/video TV modulators, and distibution amps. At one point Transifier was bought by Pico Macom, but that union did not last. Mr. Setchell is believed to have bought his company back and continued building MATV components. |

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! Andrew Box Attachments

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. Andrew |
