"Wholesale Radio Cervice Co. Inc." writes: "Super-Efficient Circuit --- Lafayette-Designed", going on with: "In our research laboratories, where we have available every conceivable type of testing apparatus, Lafayette engineers have developed this amazing new receiver. It is a distinctly new circuit design that gives the Challenger a tremendous advantage over all other receivers that may appear to be the same.". Two knobs, illuminated drum scale.
