The proposed collection of tube radio receiver circuits in compressed form presents circuits that have proven themselves in practice. To achieve a good result, indications of the size of the parts and useful times are given. When choosing and classifying schemes, the methodology and clarity are observed, which are necessary to guide the lover through the labyrinth of new schemes constantly presented to him, which are only more or less successful modifications of classic types. An amateur who wants to receive a radiotelephone transmission from local stations to a headset usually starts working as a receiver with a crystalline galena detector. Having no equal in purity, the audibility of the apparatus with a galena detector becomes insufficient as it moves away from the transmitting station.
