The EL84 is a thermionic valve of the power pentode type.
JJ Electronic – EL84 – 6BQ5
It is used in the power output stages of audio amplifiers, most commonly now in guitar amplifiersbut originally in radios. The EL84 is smaller and more sensitive than the octal 6V6 that was widely used around the world until the s. 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. Eliminating a preamplifier triode in radios made them cheaper.
Manufacturers were quick to adopt it in general use, and they are found in many old European valve radios and other audio equipment. A single EL84 was used in low-cost equipment, and a push—pull pair for lower distortion and higher power.
In common with all ‘E’ prefix tubes, using the Mullard—Philips tube designationit has a heater voltage of 6. It can produce 17 W output in Class AB1 in push—pull configuration. 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.
Other equivalent tubes are the and A dataaheet 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: As dataxheet [update] a slightly modified version of the 6P14P was manufactured in Russia for Sovtek. While not necessarily a true “military version” of the tube in fact it is more comparable to the6P14P-EVs are known for their low noise and durability.
The 6GK6 has nearly equivalent operating characteristics with a different pinout.
The Sovtek EL84 is often sold under their own brand name by other well-known electric ratasheet and guitar amplifier manufacturers – such as Fender or Mesa Boogie. From Wikipedia, the free encyclopedia.
