Radio "Malchish" (second option) from the radio designer since 1989 produced the Experimental-experimental school plant "The Seagull". The second version of the Malchish radio constructor was developed on the basis of the previous radio constructor and is a set of radio components, components and a housing for assembling a direct gain receiver operating in the LW range. The electrical circuit was switched to silicon transistors instead of germanium in the first model. Transition and output transformers removed. A properly assembled radio began to work almost immediately after turning on the power. The designer was produced until the spring of 1992. Only the types of radio components changed. The color of the case had a narrower gamut and less bright in comparison with the first option. Hams assembled a radio on a makeshift printed circuit board. In 1990, the receiver circuit was changed. The detector stage on the transistor was replaced by diodes and now the receiver has become 6 transistor. The receiver with a modified circuit was produced in conjunction with the usual 7-transistor circuit, but in much smaller quantities. And another interesting fact. At the end of the release of the first version of the receiver, it was produced for some time in the packaging of the second version. Probably a transitional model or the sale of the remnants of sets that have run out of boxes. This information about the radio was provided by Igor Kuleshov, Moscow.
