Look for I. C. A. Experimental Television Equipment

That's pretty neat! Thanks for the info. The scanning disk would be pretty easy to replicate. In fact, the whole unit could be easily made, except for the tube. It would be tempting if I had time.

Is the Television Lamp a gas discharge type tube? Or does the square plate have a phosphor on it like an eye tube? Either one could probably be modulated fast enough.
