Homemade, Homebrew CRT Valve TV Reveal

[@elek101]

This is epic. I have a similar tube in my closet, i wonder how hard it would be to get it to show a picture

Please do show more of this. I take it the Russian CRO tube has long phosphor persistence? I suppose it's something you could develop over time when you get spare time. Trying different valves and maybe introducing proper sync sep. Are you feeding a composite signal in directly or a modulated signal through a tuner, does it use DC restore for the video and is there any buzzing on sound? All these questions could be answered in another video I suppose 😄

@@radio-ged4626 sync circuit is more of a sync clipper really. I think I’d like to leave this as is. I’ve been messing about with values and so on since I made that last video, still and probably will always be doing it! No DC restoration, composite direct but I thought about building a tuner. By far the most fun achievement is actually getting something on the tube, with reasonable linearity. I’ll see if I can make a nice video over the weekend 👍🏻

Is it using electrostatic deflection?

[@radio-ged4626]

@@genenomidic1393 Not sure about Russian CROs but I would guess yes it is electrostatic.

Could you connect an snes to it and play F-zero or R-Type 3? I would be particularly interested in the afterglow of the R-Type laser on a tube like this.
