“Gauja” ( Latvian: Gauja - the name of a river in Latvia ) is a Soviet portable transistor radio receiver , one of the first to be released in a large series and the first to be produced at the Riga Radio Plant named after A.S. Popova (RRR) . Start of production - January 1961, end - 1964, about 300 thousand units were produced.
Design by Adolf Irbitis .
Specifications
"Gauja" is a superheterodyne receiver designed to receive signals with amplitude modulation in the ranges of long (150 ... 350 kHz) and medium (520 ... 1600 kHz) waves. It is assembled on six germanium transistors and one diode . The antenna is magnetic , built-in, on a flat ferrite rod. Nominal supply voltage is 9 V ( Krona battery or 7D-0.1 battery ), operability is maintained at 5.6 V. The maximum output power is 150 mW. Dimensions 162 × 98 × 39 mm. Weight with battery and leather case 600 g.
There are three controls: a control knob (large diameter, without vernier , mounted directly on the axis of the tuning capacitor ), a volume control combined with a switch, and a range switch. Connecting an external antenna and headphones is not provided.
“Gauja” was produced in two versions - with and without a battery charger. In the version with the charger, a rectifier on one diode and a connector were located in the receiver case, the kit included a cord with a special plug for connecting to a 220 or 127 V. network. The plug contained quenching resistors and a voltage switch. The charger does not contain an isolation transformer; during its operation, the receiver elements are galvanically connected to the network. Battery option cost 52 rubles. 90 kopecks , the usual - 43 rubles. 70 kopecks
In 1963, the plant began to produce a more advanced model of the same Selga class, and both receivers were simultaneously produced for some time. “Gauja” was quite popular, it can be seen in the movies of the 1960s (“ Three plus two ”, “ Three poplars on Plyushchikha ”, “ Watch out for the car ”), as well as in the later ones - “ Big Break ”, “ Black Cat” , white cat "," Dogs "
