Are thermionic diodes allowed or just semiconductor diodes? What about the early crystal diodes (subset of semiconductor). Did the Colossus computer count? Eniac? I guess particular items don’t matter because no individual owns either and I doubt individual built replicas.
Vacuum tubes (thermionic valves) were the first active electronic components… and by the 1920s, commercial radio broadcasting and telecommunications were becoming widespread and electronic amplifiers were being used in such diverse applications as long-distance telephony and the music recording industry.
At least one diode.
How do you figure?
Vacuum tubes are called triodes, pentobes, etc depending on how many whatevers it has, do those count?
Yes, because there will be at least one “whatever.”

Per that definition:
So tubes are in! Old lamps are OUT!
Relays?
