[RadioSvit]

Arran, thank you for the interesting information. Here is a diagram of this radio.

   

This radio has two vacuum tubes, it was made in 1939 by the Latvian state company VEF. Despite the fact that the scheme is very simple, this radio has three bands - Long Waves, Middle Waves (Brodcast) and short waves. But you will be surprised when you find out that its body is not bakelite or plastic, but ... wooden! This company owned a furniture factory and did not have the technology to make plastic and carbolic cases, so it imitated them from wood! And they succeeded - their receivers looked like carbolics!
