VR Tube Information
Correctly-operating VR tubes glow during normal operation. The color of the glow varies depending upon the gas mixture used to fill the tubes.
Though they lack a heater, VR tubes often do become warm during operation due to the current and voltage drop through them.

Famous quotes containing the words tube and/or information:
“Even crushed against his brother in the Tube the average Englishman pretends desperately that he is alone.”
—Germaine Greer (b. 1939)
“The information links are like nerves that pervade and help to animate the human organism. The sensors and monitors are analogous to the human senses that put us in touch with the world. Data bases correspond to memory; the information processors perform the function of human reasoning and comprehension. Once the postmodern infrastructure is reasonably integrated, it will greatly exceed human intelligence in reach, acuity, capacity, and precision.”
—Albert Borgman, U.S. educator, author. Crossing the Postmodern Divide, ch. 4, University of Chicago Press (1992)
