Best El84 Vacuum Tubes — FAQ

How long do EL84 tubes last?

Preamp should last anywhere between 2 to 3 years, while the rectifier tubes should last for even more than 5 years in that case. This means that if you're practicing guitar twice a week, you should expect it to last much longer. In fact, some players claim that EL84 tubes can last for 5 to 10 years before wearing out.

Nevertheless, 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).

On the other hand, how often do vacuum tubes need to be replaced?

On average, tubes can last from 500 to 1,000 hours, so if you play with your amp two to three hours every day, you can safely expect to get around a year or less from your vacuum tubes.

Similarly, do vacuum tubes need to break in?

Yes, they do break in. Do they NEED a break in? Not really. Small signal tubes especially will sound good within a few minutes of warming up but they will tend to sound better after a while because everything gets "baked" and molded into shape so to speak.

However, who makes EL84 tubes?

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.

Thus, what is the difference between EL34 and EL84?

The EL34 is larger and it puts out two to three times the wattage as the EL84. More watts equals more volume, more headroom, and a better frequency response even at low volumes. Lower bass frequencies require more power, and the higher wattage of the EL34 is better able to handle the full frequency spectrum.

Indeed, can I swap EL34 for EL84?

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.

Still, can you swap EL84 for 6V6?

Yes, the socket change is a fairly major operation, but the 6V6s are pretty compatible with the EL84 voltage and output impedance.

And, how many watts is an EL84?

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.

Likewise, how do you know if a vacuum tube is bad?

Sometimes you will hear strange sounds, loss of power, or heavily distort sound. These are signs that a tube is failing. Often power loss that seems like the amp is performing at half power or less will be one or more bad power tubes, or even a dying phase inverter tube.

Also, how do you know when your power tubes need replacing?

A: These are the most common signs that tubes need replacement:

  1. Excessive noise (hiss, hum) including squealing or microphonic tubes.
  2. Loss of high end.
  3. A muddy bottom end; Sounds like there is too much bass and note clarity is lost.
  4. Erratic changes in the overall volume.
  5. The amp doesn't work!

Nonetheless, can I replace power tubes without biasing?

To change preamp tubes, all you'll need is a screwdriver and a little know-how.With preamp tubes, you don't need to worry about things like biasing or using matched pairs as you do with power tubes. As long as your new tube is the same model as what you're replacing (12AX7, 12AT7, 6SN7, etc.), you're good.
