The &quot;Malchish&quot; radio receiver (the second version) from the radio designer has been produced by the Chaika Experimental School Plant since 1989. The second version of the Malchish radio designer was developed on the basis of the previous radio designer and is a set of radio components, assemblies and a housing for assembling a direct amplification receiver operating in the LW range. The electrical circuit was converted to silicon transistors instead of germanium in the first model. Removed transition and output transformers. A properly assembled radio started working almost immediately after turning on the power. The designer was produced until the spring of 1992. Only the types of radio components were changed. The body color had a narrower range and less bright, in comparison with the first version. Radio amateurs also assembled a radio on a homemade 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 a 6-transistor one. 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 released for some time in the package of the second version. Probably a transitional model or selling leftover kits that have run out of boxes. This information about the radio was provided by Igor V. Kuleshov, Moscow.
