Are sovtek EL84 tubes any good?
Sovtek EL84 are extremely reliable and good sounding. The construction has improved steadily over the years.
What tubes are compatible with EL84?
The EL84 is smaller and more sensitive than the octal 6V6 that was widely used around the world until the 1960s. An interchangeable North American type is the 6BQ5 (the RETMA tube designation name for the EL84).
Are JJ amp tubes good?
JJ EL34 tubes are very reliable and sound good too, but be careful to get EL34 tubes and not E34L tubes unless your amp was specifically designed for them. Tung Sols are good but a bit more expensive.
Are EL34 and EL84 interchangeable?
In the specific case of swapping an EL34 for an EL84, you actually can’t swap them because the two different tubes have a different number of pins on their sockets.
Where are JJ tubes made?
Slovakia
JJ Electronic, s.r.o is a Slovak electronic component manufacturer, and one of the world’s remaining producers of vacuum tubes. It is based in Čadca, in the Kysuce region of Slovakia.
Is a 7189 the same as an EL84?
The 7189 industrial tube is similar to the common EL84 (European) or 6BQ5 (American) 9-pin power pentode. But the 7189 is designed for circuits operating in the 400 volt range. The EL84/6BQ5 is designed for the 300 volt range.
Do power tubes need to be matched?
Power tubes require matching because the way they amplify signal can create exceptionally bad sound if they are poorly matched, but pre-amp tubes generally aren’t used this way and so matching them is unnecessary.
Is EL84 same as 6V6?
6V6 and EL84 are almost bound to have a similar required anode load because they are designed to run similar power from a similar supply voltage. EL84 may be more linear, but it has a reputation for short life probably because it just runs too hot.
Are JJ tubes made in Russia?
JJ Electronic, s.r.o is a Slovak electronic component manufacturer, and one of the world’s remaining producers of vacuum tubes. It is based in Čadca, in the Kysuce region of Slovakia.
Where are sovtek tubes made?
Saratov, Russia
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.
How many watts is an EL84?
17 watts
Originally designed for the output stages of audio frequency amplifiers, the EL84 can deliver up to 17 watts. Although it is physically smaller than most common output tubes, this pentode tube can really deliver.
Are Chinese vacuum tubes any good?
Modern Chinese Vacuum Tube Amps can be very good but are restricted by the cheap mass market valves that are produced purely for consistency and cost restraints. Chinese Tubes such as 6J1, for instance are a direct copy and hence a direct equivalent of Russian 6J1P etc, etc.
Do matched tubes make any difference?
Power tubes are electrically matched so each tube will have the same amount of “idle” plate current and amplification characteristics when used in an amplifier. This is done so the tubes can work together in your amp giving you optimal sound quality and tube longevity.
How do you know if your tubes are matched?
To be specific, mis-matched tubes can be bias-adjusted so that output sound is centered. However, if the tubes aren’t a true match, then one channel will not sound as “lively” as the other – sort of like a dead can. With experience, this is easily discernable by ear.
Can you put 6L6 tubes in a EL34 amp?
Re: 6L6 to El34 tube change
One if the PT’s heater current capacity. 6L6 heaters draw 0.9A each whereas EL34 heaters draw 1.5A, so a pair of tubes will add an additional 1.2A to the heater supply requirement. Two is the output tube socket wiring.
Are JJ tubes made in China?
Who owns Sovtek tubes?

How much current does EL84 draw?
EL84’s draw 45 mA plate + 10 mA screen max in a typical Rocket-class amp, so a PPP with 4x output tubes and 3x ECC83’s should be rated for 200 mA minimum (the amp is class AB, with only two EL84’s drawing current above idle).
Are JJ tubes still being made?
In 1994, JJ Electronic started with the production of three types of tubes. Nowadays, JJ electronic offers an assortment of more than 40 types of vacuum tubes.
Do I need matched power tubes?
How important is it to match tubes?
Do you need matched tubes?
Power tubes, unlike preamp tubes, do generally need to match. This is because each power tube needs to have an identical account of idle plate current. The amplification characteristics of the tubes also need to match up when they are used in a guitar amp, for example.
What tubes can replace 6L6?
One thing worth noting is that many folks consider the KT66 tube to be a substitute for the 6L6 tube types. Although this is acceptable in some circuits they are not direct substitutes. The 6L6 tube type has a heater filament that draws approximately 0.9A of current. The KT66 draws about 50% more current, 1.3A.
What do 6L6 tubes sound like?
Sound Differences
The 6L6 has a warm, full-bodied tone that is well-suited for blues, country, rock, and metal. This is normally referred to as an American tone in the guitar music communities. This is primarily because of the higher headroom and more present midrange that offers a more versatile, yet full sound.
Is Sovtek Russian?
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.
