Radioconstructor '' 4 options ''.
Radio and electrical constructors, sets.Radio receiving devicesThe radio designer "4 variants" was produced presumably since 1967 by the Riga enterprise. The radio constructor is similar to the "From simple to complex" set of the same enterprise, the page of which is available on the site. Four constructions can be assembled from the "4 options" radio constructor: a detector receiver; detector receiver with RF amplifier; a direct gain receiver with a single-ended output; and a forward-gain receiver with a push-pull output. The last two schemes can be assembled in a beautiful case with the name "Jura". First cosmonaut Yuri Gagarin.
