The 5 Best EL84 Tubes – Noisylabs

What are El84 tubes?

El84 tubes are a tube amp we have never mentioned before. These tubes work with vacuum tube based amps and they help the sound of your system. 

The intention of creating the EL84 was to provide more gain than average. Once it was created, it was common to see it in different audio systems. Its advantages include sound warmness, more power, and lower distortion. 

Common applications for El84 tubes

El84 tubes can be found in guitars or radios. They are used as an alternative to bigger audio tubes. This is why a lot of radios transitioned to them. Switching to a smaller tube means less heat for the circuit, and it means more space to bring in more components for audio.

There is one brand in particular who built a successful product line thanks to the el84 tube, and that's Vox. Thanks to the el84 tube, Vox's guitar tube amps have never gone out of style.

The el84 tubes were found in radios first, and then guitar amps. Other than these 2, you won't find el84 tubes in many other places. Their scarcity in the market makes it a little harder to find a good one. This is why knowing the lifespan of one will help you get started on your journey to find another one.

How long do El84 tubes last?

There isn't an arbitrary number for how long these tubes last. Just like any other material object, it depends on how you treat them. We know someone who still has the iPhone 5, and while it looks ugly, at least it still works.

While we don't know how long the tubes will last, there are some precautions you can take to ensure they last a long time. One of the first things you can do is to turn the tube off right away when you're done using it.

Make sure to turn the amp on 30 minutes to an hour before playing music so it warms up. Turning the amp on and off takes a toll on the tubing. 

It's important to remember the average life span for a tube is 1-3 years. The difference in time depends on how well you treat it. While you don't know how long an EL84 tube well last, there are signs that'll let you know when it's time to change.

If your tube makes a noise other than the one you're accustomed to, you might want to change tube. If your tube distorts your music, think about changing your tube. Finally, if your amp loses its high end, you should think about changing your tube.

Qualities to look for?

What do you want?

You have to figure out what type of tube you want. Each tube means different sounds. EL84 tubes are warm sounding. They're easy on the ears and go great with harmonies. If this is what you're looking for, then a EL84 tube is for you.


Next up is determining if your tubes will match your amps. You have to understand how much wattage power you need, and if it's compatible with your amp. This is critical when matching your speakers with your amplifiers. Too much power will overwhelm the amp leaving you with a broke tube and amp.


Another factor is pricing. Fortunately, tubes aren't ridiculous when it comes to money. But, like every marketplace, there are going to be more expensive products than others.


There are tradeoff you're going to make when choosing tubes. Some will be more expensive than other, but it might not fit the wattage power you want. One quality we advise you not to sacrifice is durability. Compromising durability just ruins everything else. Watts, tone, and pricing don't matter if it breaks right away.
