| Notes | The DuMont RA-103 series of televisions (or "Telesets" as DuMont called them) are popular with collectors because of their high quality electrical design and interesting cabinets. All RA-103 models have a 12 inch round CRT and a continuous tuner with a triple roller inductor that covers the VHF low, FM radio, and VHF high bands in one continuous range (44-216 MHz). The tuner is a Mallory "Inductuner" and was referred to as an "Inputuner" by DuMont. Early versions of the RA-103 had a 6U5GT or 6G5GT tuning eye (according to Rider TV vol. 1), but most sets found today have a 6AL7GT tuning eye as original equipment. The first models of the RA-103 family were introduced in 1947. The RA-103 Chatham, a mahogany table model with an unusual trapezoidal shape (nicknamed the "Doghouse") seems to be the most commonly found today. The RA-103 Stratford is a table model with doors (see Rider TV vol. 1). The RA-103 Meadowbrook is a mahogany console with no doors, the CRT in the upper left, and a 10-inch speaker center bottom. The RA-103 Savoy is a larger mahogany AM/FM/TV/Phono console with doors, having the CRT top center, AM tuning dial on the left, FM/TV tuning dial on the right, speaker bottom left, and phonograph (Webster model 56 record changer) bottom right. The Rider TV index also lists an RA-103 Sutton, but no further information about this model is available. The series was updated at some point with the RA-103C Savoy (same cabinet as RA-103 Savoy) and the RA-103C Winthrop (similar to Savoy, but with knotty pine cabinet). In 1949, the RA-103D series was introduced, with significant circuitry changes and some different tubes. The RA-103D Rumson is a mahogany table model with a rectangular profile and a square tuner window (prior to the RA-103D models, the TV/FM tuning windows were round). There are also two consoles, the RA-103D Sheffield and RA-103D Canterbury, both of which are known to be consoles because of their 10-inch speakers documented in Rider TV vols. 3 and 4. The RA-103D chassis is very similar to the chassis used in the RA-104A Hastings and RA-110A Wellington sets, which had 15-inch and 19-inch CRTs, respectively. |
