In this short excerpt from the 4th part of my nostalgia Heathkit IT-12 build I briefly explain the structure and function of the magic eye display tube. Enjoy!

    Ich wollte Wissen ob ich die 6E2 ersetzen kann durch eine EM800. Ist der Sockel gleich und die Pinn Belegung. Oder muss die Platine angepasst werden? Oder geht es gar nicht? Danke

    I wanted to know if I could replace the 6E2 with an EM800. Is the socket the same and the pin assignment. Or does the board have to be adapted? Or is it not possible at all? Thank you

    I am just old enough to say that "in the old days, when I was young" I was playing around with these tubes a lot.
    At one moment in time, everyone was throwing out those old radios with tubes so we had enough of this stuff to play with. Had a great time back then, thanks for reminding me 😉

    Did Fran EVER actually explain what the hect this is is supposed to DO? I can only find this video and part three. Both go into detail about parts of the tube, but NEVER say what the purpose is. I have not found any videos of the completed projeject or demonstration of the tube in action.I have seen a video, from someone else, showing the top of the tube fluorescing with a pale greenish light, but he did not say what the tube was supposed to do, either.

    How come you didn't actually run power to this? I had to go to a different channel to see it in action… : |
