      1905 is a milestone of modern physics, because it’s when Special Relativity came out.

      That’s older than the transistor, which was commercialized in 1951. But it’s also older than the vacuum tube triode, which was invented in 1906 or 1908.

      In 1905, there were no amplifiers of any kind (though there were relay switches). There was almost no radio. The triode was a necessary invention for almost all of analog electronics.

        Meh, you could do signal amplification via transformers and tuned resonators.

        It sucked, but it was possible.

        That’s how we had telephones before we had tubes.

          Transformers can increase voltage while decreasing current, or increase current while decreasing voltage, but can’t increase a signal’s power.

            I know, but this just means you start with a very high current signal.

            You lose a lot, but again it’s what we had before transistors.

            It’s basically blood magic.

            It’s signal amplification by cannibalizing other band stop signals.

          Like a transistor only larger, less efficient and more fragile.

        The wright brothers flew almost 2 years before special relativity came out.
