It was suited only to a limited range of audio frequencies - essentially voice frequencies. [23] The triode was the first non-mechanical device to provide power gain at audio and radio frequencies, and made radio practical. Triodes are used for amplifiers and oscillators. Many types are used only at low to moderate frequency and power levels.
The Audion was a considerable improvement on this, but the original devices could not provide any subsequent amplification to what was produced in the signal detection process. The later vacuum triodes allowed the signal to be amplified to any desired level, typically by feeding the amplified output of one triode into the grid of the next ...
A SET tube audio amplifier. A single-ended triode (SET) is a vacuum tube electronic amplifier that uses a single triode to produce an output, in contrast to a push-pull amplifier which uses a pair of devices with antiphase inputs to generate an output with the wanted signals added and the distortion components subtracted.
Lee de Forest (August 26, 1873 – June 30, 1961) was an American inventor, electrical engineer and an early pioneer in electronics of fundamental importance. He invented the first practical electronic amplifier, the three-element "Audion" triode vacuum tube in 1906.
The Triode Audion was not invented in 1906, and it never produced any linear amplification until around 1912. ... Indeed: the primary failure mode was the gas being ...

It belongs to a large family of dual-triode vacuum tubes which share the same pinout (RETMA 9A). 12AU7 is also known in Europe under its Mullard–Philips tube designation ECC82 . [ 1 ] There are many equivalent tubes with different names, some identical, some designed for ruggedness, long life, or other characteristics; examples are the US ...
