I don't speak or read Russian, but if this is about Sputnik-1, it is clear that the Tx has 3 tubes, answering one question!

Lots of interesting stuff in the wikipedia article: https://en.wikipedia.org/wiki/Sputnik_1#Design but it does not say what the active device was. A 1 watt transmitter in 1957? Must have been tubes, no?
An interesting thing I did not know: It was filled with nitrogen and used a fan to cool off the electronics!

Awesome!! Thank you, Bruce!!
What kind of devices did they use for transmitting this signal? I wonder transistors were good enough for this frequency, but.... vacuum tubes??
