    There are three stages of radio frequency and a detector. One volume and one clarity control. "The model has a solid walnut panel front and in the opening is a green-black soft finish panel on which rests the beautiful shaded bronce plates opening on the single illuminated drum on the left side of which is numerical spacing and on the right an erasable space for logging. A center knob on the Gothic escutcheon plate tunes the entire receiver with air-line selectivity". "In a separate unit is the audio frequency end using two stages of resistance coupled amplification and one stage of power transformer rendering the most tremendous volume and a fine sliky, full, well-rounded tone."
