Notes
The DuMont RA-105 family of 15-inch round CRT TV receivers (or "Telesets" as DuMont called them) have a continuous tuning Mallory-Ware Inductuner (called an "Inputuner" by DuMont) using a triple roller inductor which covers the VHF low, FM, and VHF high bands in one band from 44-216 MHz. A 6AL7GT tuning eye is also provided. The chassis has main unit and a subchassis for HV flyback power supply with voltage doubler.

There are five models in the family, including the RA-105 Stratford (1948) TV/FM table model (available in mahogany and blonde) with a 6 inch speaker, the RA-105 Westbury (1948) and Whitehall (1948) TV/FM mahogany consoles with 12 inch speaker, the RA-105 Colony (1948) TV/FM/AM/phono mahogany console with 12 inch speaker and separate AM tuner chassis, and the RA-105B TV/FM Sussex (1949) mahogany table model.
