[RadioSvit]

Hello everyone. Again about the exhibits of my collection ..

An interesting three-tube radio receiver of the regenerator type of the Swedish company SRA Radiola model 342LV 1934. A feature of this model is a universal transformerless power supply for operation in AC and DC electrical networks. But even more interesting is the second feature - the use of English 7-pin metal Catkin radio tubes with an external anode! A very interesting design. Due to their high manufacturing cost in household appliances, they were used only for a few years, and then they were replaced by ordinary glass cylinders. But they were used in military radio equipment for a very long time.
As for the design, it is strictly classic for a Swedish product of the 30s, simple rectangular shapes and veneer of expensive wood species in the decoration, in this case - Karelian birch veneer. And this is in a budget radio receiver...
