In electronics, a vacuum tube, electron tube (in North America), thermionic valve, tube or valve is a device controlling electric current through a vacuum in a sealed container. The container is often thin transparent glass in a roughly cylindrical shape. Within the glass is a vacuum with a cathode and anode at either end. Electrons flow from the cathode to the anode through the vacuum, a demonstration of the Edison effect. The introduction of a grid between the cathode and anode makes it possible to amplify a current. A negative voltage applied to the grid will subdue the current traveling between cathode and anode through the vacuum by a larger value than the current applied to the grid. Hence the grid may be used to modulate the current through the tube.
Vacuum tubes are used for rectification, amplification, switching, or similar processing or creation of electrical signals. Tubes rely on thermionic emission of electrons from a hot filament or hot cathode. Electrons travel to the anode (or plate) when it is at a positive voltage with respect to the cathode. Additional electrodes between the cathode and anode regulate current, allowing a tube to amplify or to switch.

There were two versions of this film made; this is the short version. Watch for footage of the ridiculously huge vacuum tubes that were used for radio transmission.
From the original 1940 documentation:
"With Western Electric Vacuum Tubes in the starring roles, this film tells the fascinating story of tube development from the first crude bulbs of Edison and De Forest to the powerful and efficient tubes in use today, and shows the prominent part they play in radio, long-distance telephony, public address systems, sound motion pictures and the phonograph.
Animated sequences depicting a traffic cop halting an on-rush of electrons inside a tube and a troupe of monkeys tossing pebbles at a grid explain the three-element tube so clearly that a non-technical audience can understand how it operates.
Scenes in the tube shop show the precision workmanship that goes into the making of broadcasting and telephone repeater tubes. The camera moves from one intricate operation to another while skilled craftsmen transform spools of wire and rods of glass into these magic lamps of today."

- Updated: 03 May 2014
I have been asked a lot of questions over the years about transformers and this is my attempt to answer the basics - transformer/magnetics design is an engineering field all in its own so there are no YT videos that will make transformers a simple subject - I hope this helps the vacuum tube audio amplifier builder.
Here is another link that might help - http://www.ozvalveamps.org/optrans.htm

AT&T; Archives: A Modern Aladdin's Lamp, about vacuum tubes,1940
See more from the AT&T; Archives at http://techchannel.att.com/archives There were two versions of this film made; this is the short version. Watch for footage of the ridiculously huge vacuum tubes that were used for radio transmission. From the original 1940 documentation: "With Western Electric Vacuum Tubes in the starring roles, this film tells the fascinating story of tube development from the first crude bulbs of Edison and De Forest to the powerful and efficient tubes in use today, and shows the prominent part they play in radio, long-distance telephony, public address systems, sound motion pictures and the phonograph. Animated sequences depicting a traffic cop halting an on-rush of electrons inside a tube and a troupe of monkeys tossing pebbles at a grid explain the three-element tube so clearly that a non-technical audience can understand how it operates. Scenes in the tube shop show the precision workmanship that goes into the making of broadcasting and telephone repeater tubes. The camera moves from one intricate operation to another while skilled craftsmen transform spools of wire and rods of glass into these magic lamps of today."
