Eliminating a preamplifier triode in radios made them cheaper. It can datashert 17 W output in Class AB1 in push—pull configuration. This article needs additional citations for verification.
Retrieved from ” https: Retrieved 23 May The EL84 is smaller and more sensitive than the octal 6V6 that was widely used around the world until the s. Retrieved 22 May The EL84 was developed to eliminate the need for a driver tube in radios, so it has rather more gain than is usual in a power pentode. The 6GK6 has nearly equivalent operating characteristics with a different pinout.
Vacuum tubes Guitar amplification tubes. The EL84 is a thermionic valve of the power pentode type.
Other equivalent tubes are the and A  an extended-ratings version of the tube for industrial applications, E84L long life, professional version with more than hours expected lifetime and the directly equivalent 6P14P Cyrillic: A single EL84 was used in low-cost equipment, and a push—pull pair for lower distortion and higher power. It is used in the power output stages of audio amplifiers, most commonly now in guitar amplifiersbut originally in radios.

As of [update] a slightly modified version of the 6P14P was manufactured in Russia for Sovtek. Manufacturers were quick to adopt it in general use, and they are found in many old European valve radios and other audio equipment.
The Sovtek EL84 is often sold under their own brand name by other well-known electric guitar and guitar amplifier manufacturers – such as Fender or Mesa Boogie.
Developed by Philips in for use in the British Mullard amplifier, [ citation needed ] the EL84 came to prominence when used in Watkins and later the Vox amplifiers preferred by many British Invasion bands of the s.
