To promote their new 9-pin tubes EZ80, EF86 and EL84, the Anglo-Dutch Mullard Company developed, in 1954, a famous and very popular mono amplifier circuit, the Mullard 5-10. The design featured 5 tubes with 10 watts output: EF86 as preamplifier, ECC83 phase-splitting, two EL84 in push-pull configuration, EZ80 rectifier. The amplifier used the ...
The EL84 is a vacuum tube of the power pentode type. It is used in the power-output stages of audio amplifiers, most commonly now in guitar amplifiers , but originally in radios. The EL84 is smaller and more sensitive than the octal 6V6 that was widely used around the world until the 1960s.

This makes them unsuitable for use with valve amplifiers, particularly lower-power single-ended designs. Valve hi-fi power amplifier designs since the 1970s have had to move mainly to class AB1 push–pull (PP) circuits. Tetrodes and pentodes, sometimes in ultra-linear configuration, with significant negative feedback, are the usual configuration.
Sovtek is a brand of vacuum tube owned by Mike Matthews's New Sensor Corporation and manufactured in Saratov, Russia. They are often used in guitar amplification and include versions of the popular 12AX7, EL84, EL34, and 6L6 vacuum tubes. Many of the vacuum-tube amplifiers in modern production are factory-fitted with Sovtek valves. [1]
The pentode EL84/6BQ5 - 9 pin Noval base tube, that although different enough from the 6V6 not to justify rating it as an equivalent, because of its popularity and ready availability, plus having a close-enough similarity to make it possible, if bias is altered, adapters have been developed commercially to allow an amplifier designed for 6V6 ...
There are two variations of the "Delta Blues" model, the Delta Blues with one fifteen-inch speaker or two ten-inch speakers. They use 12AX7 preamp tubes, EL84 power tubes, and have spring reverb tanks. From 1994 to 1997, a 15 watts amp with a 10 inches speaker was also produced, the Peavey Classic 20.
