JJ EL84 PDF

Once you start to push a little air, however, your amplifier will show off what it can do and the power tube will display its individual characteristics more. Keep in mind, that by using pedals, you can make one amp sound pretty much like any other one, so this discussion is focused on how a few of the most popular power tubes differ from each other when using the amp, and not the pedals, to get your sound. So, here is a rundown of how these tubes differ in sound. EL84 Power Tube The EL84 tube has a snarly sound bright with midrange punch , and is usually found in smaller wattage amplifiers. They break up faster than any of the three power tubes mentioned here and have the least amount of headroom. EL84s can be brighter than the EL34 and have a bit less low-end.

Once you start to push a little air, however, your amplifier will show off what it can do and the power tube will display its individual characteristics more. Keep in mind, that by using pedals, you can make one amp sound pretty much like any other one, so this discussion is focused on how a few of the most popular power tubes differ from each other when using the amp, and not the pedals, to get your sound.

So, here is a rundown of how these tubes differ in sound. EL84 Power Tube The EL84 tube has a snarly sound bright with midrange punch , and is usually found in smaller wattage amplifiers. They break up faster than any of the three power tubes mentioned here and have the least amount of headroom. EL84s can be brighter than the EL34 and have a bit less low-end. In America, these tubes are known as 6BQ5. They were first produced for radios, helping to eliminate the need for a driver tube and as an inexpensive alternative to the larger audio tubes of the time.

The EL34 is larger and it puts out two to three times the watts as the EL84s. More watts equal more Volume, more Headroom, and a better Frequency response, even at low volumes. Bass needs power, and the higher wattage of the EL34 is what leads to the warmer tone as the tube is better able to handle the full frequency spectrum. The increased headroom can lead to a more open and less compressed sound than that of the EL84s. Consequently, you do get a little less headroom and they break up earlier than 6L6 tubes.

Summary Start by listening to your own playing. You probably want the natural breakup of the tubes to distort your sound and give you that warm crunch that made you want to play the guitar in the first place. And EL34 and EL84 tubes just enhance natural amp distortion so nicely and drive the amp so well.

The idea is to get that unbeatably clean tone with infinite headroom, and add pedals to get any sound that you want. And keep in mind that as much as power tubes differ, amplifiers differ as well, so the overall voice and behavior of the power tube will vary, depending on how the amplifier is designed. If you want to really get a feel for how these tubes differ in sound, get your hands on something like the Mesa Lone Star, which can use both the EL34 and 6L6 power tubes.

Only the machines are the same, and in the Tesla days they were new, and now they are old. The used materials definitely are not the same. Also wires, and nickel technology came from Tesla plants that are all closed now. They are regarded something different, which is correct.
