Knight Span Master
Allied Radio Knight Kit model Y-258. This transformer-operated radio makes its first appearance in Radio-TV News in the Allied Radio ad of September 1958. Priced at $24.95, the ad describes the dual regeneration controls, coarse and fine, as well as the bandswitch, bandspread, and "easy to build kit" nature of this four band regenerative receiver. This is a two-tube set (plus selenium rectifier) with very efficient use of those tubes, 6CB6 as RF amplifier/detector and 6AW8 as audio amplifier. The set is surprisingly good at picking up short wave broadcasts as well as the BC band at speaker volume with about 20 feet or more of wire as an antenna.
