- Notes
- The DuMont RA-104 family of TVs (or "Telesets" as DuMont called them) uses a chassis similar to the RA-103D models but used a larger 15-inch 15DP4 CRT. Like all early DuMont Telesets, they use a Mallory-Ware Inductuner (referred to as a "Inputuner" by DuMont) with triple roller inductor to tune the VHF low (including Channel 1), FM, and VHF high bands in one continuous 44-216 MHz band.
The RA-104A Hastings is a TV/FM table model, available in both mahogany and blonde. The RA-104A Wellington is a TV/FM/AM/phono console, also available in both mahogany and blonde, with one of the first 3-speed automatic record changers.
