This radio has a very unusual AC/DC circuit design, perhaps a study in how to make an "All American Seven" circuit. With its push-pull audio output stage and large speaker, this set's audio performance is very strong, with a powerful sound. I can imagine the original purchaser being quite proud of his "deluxe" plastic AC/DC radio.
