Notes The DuMont RA-108 family of 19-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 two models in the family. The RA-108A Bradford is a TV/FM/AM/phono mahogany console. The RA-108A Mansfield is a TV/FM console. Both were introduced in 1949.
