Not tested, not connected to the mains. I don’t know the condition of the components, capacitors, that’s why I didn’t turn on the radio to avoid damaging something. The radio is made of bakelite – it is not damaged or cracked – it has a nice preserved burgundy shade (you need to polish the radio). Buttons for switching ranges broken – see photo.

Bakelite cabinet, plastic mask, glass scale. Sputnik is the name of a series of space satellites launched by the Soviet Union since the end of the 1950s.
