Paragon RB-2A Battery 3 Tube Radio. The Paragon RB-2A came out near the end of 1923. It was designed by Paul Godley. The set, although a good receiver, was not very successful. As a result, it is harder to find than most other Paragons. The set had an interesting characteristic: By changing a tap inside the radio you could use a variety of tubes like UV201A, UV199, WD11, WD12, UV200, UV201, and the Western Electric 216A (shown in the picture of the chassis).
