Vacuum Tube
Research
in educational (.edu) web sites.
 Lee Deforest invented the three electrode vacuum
tube amplifier, better known as the Audion, in 1906. He followed the work of British
engineer John Ambrose Fleming who had developed the first electron tube, the Diode
Thermionic Valve, in 1904. The development of the Audion made possible the
amplification of the weak signals produced by microphones, and thus, live broadcasting.
The Audion and its successors also began to alter the manner in which recordings were
made. Prior to electrical amplification, recordings were made acoustically with large horn
assemblies. By 1925, most recordings used the new electrical process.
For
those who want to tackle the challenge of building their own electrode vacuum tube
amplifier, here are some educational (.edu) web sites. Read " Tubes Mechanics & Mystique" to
understand a musician's love for tubes and why they are still used today.
