Is there any reason that amps and preamps need to match?

Preamp tubes are, in the majority of cases, self-biasing. Therefore, they do not require matching. Power tubes are an example of this. Despite the seemingly straightforward answer to this question, many audiophiles argue that matching preamp tubes do offer some sonic benefits. This is because almost all preamp tubes are self-biasing. This means that unlike power tubes, having two identically matching sides is not necessary. Changing preamp tubes within an amplifier is a good way to improve the overall sound, or achieve the desired tone.

These are the most common type of preamp tubes. Not all 12AX7 preamp tubes are identical in their makeup though. Manufacturing processes vary, as do the quality of the materials used to construct the tube. Logically, one would conclude that using two of the same make of 12AX7 preamp tubes is a good idea. But despite there being potential sonic benefits to matching preamp tubes, it is not a necessity.

Overall, the tonal difference is likely to be very minimal, and only experienced audiophiles would consider it to be essential practice to match preamp tubes. Matching refers to the process of testing multiple tubes for their transconductance level and the current draw when the preamp tube is under load.

Using 12AX7s as an example, matching these preamp tubes is a good idea, but by no means essential. These tubes, along with the 6DJ8 variety, are known as linestage tubes. When they are matched, this will ensure that you get even gain from both tubes.

The matched preamp tubes are also likely to age at the same rate, although this is not guaranteed. A common argument for matching preamp tubes is that you want them to degrade simultaneously to the same degree, to avoid imbalances occurring or unnecessarily needing to replace one of them.

A rule of thumb to follow is that a good preamp tube with a solid linestage or phono stage design should be capable of working with tubes that vary by around 20 percent. Below is a table which shows some popular tube types, and whether they need to be matched. As I previously stated, the practice of matching preamp tubes is, to a certain degree, recommendable.

However, it is not essential by any means. To get to the bottom of why preamp tubes do not need to match, we must establish the functions and basic principles of these vital devices. Most preamp tubes used in modern amplifiers are of the triode variety.

This essentially means that there are three main parts to the tube. Each of the parts plays an integral role in the function of the preamp tube, and in deciding whether they need to match. The grid in a preamp tube is the input, at which point the low-level signal controls the flow of electrons from the cathode to the plate. To increase the gain of the input signal, the output signal is commonly sourced from the plate. However, in rare instances, such as buffered effects loops, the output signal is sometimes taken from the cathode pin.

The pin, however, is incapable of supplying any gain to the input. Pentodes, for example, have five internal parts that provide screens and allow for additional control over the flow of electrons. These types of preamp tubes are rare nowadays and have mostly been replaced by manufacturers, favoring the triode variety. One thing that often confuses musicians about whether their tubes need to be matched, is the fact that there are other types of tubes than the preamp variety that are designed in significantly different ways.

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. Power tubes need to work together within an amplifier, to produce the best around quality and promoting longevity.

Matched power amp tubes use the cathode as their primary source of electrons. A filament is employed to produce the necessary amount of heat, which releases the electrons from the cathode within the tube. Electrons have a negative charge, so the plate uses a positive voltage, causing them to be attracted. Unlike preamp tubes, power tubes have a device called a control grid within them. This is positioned between the cathode and the plate and has a negative voltage, which allows it to repel the electrons and prevent them from flowing freely to the plate.

The more negative the voltage of the control grid is, the fewer electrons can pass through it. Likewise, if the grid is made less negative, the electrons pass through more frequently. This flow of electrons is measured at the plate, and that provides us with the plate current.

Materials, mechanical tolerances, signal gains, and distortion characteristics are all aspects that would be matched.

Solid-state amps, rather than using tubes, are fitted with transistors. Transistors still serve the same purpose as tubes; they do so using different technology.

They are also often much less expensive than their tube counterparts. The reason that many guitarists prefer tube amplifiers is because they are considered to produce a warmer, more authentic tone.

Tube amplifiers are characterized by their ability to add distortion. This natural-sounding break-up is highly sought after by guitarists and has been a staple of records since the early 60s when tube amps came to the forefront.

Fender generally uses 12AX7 preamp tubes in their amplifiers. All Marshall, Mesa Boogie, Vox, and Peavey use the same preamp tube as Fender, as they are the most reliable and effective choice.

Tube amplifiers are usually louder than their solid-state counterparts. The lower voltage makes it seem that the amp would be quieter, but in fact, a tube amp of 10 watts would be louder than a solid-state amp of 50 watts.

Check out my article that discusses how much electricity amps use. You can read it here. Tube amps should be given adequate time to warm up after switching them on. If they are not fully warmed up, the tone and output will suffer. Around 20 minutes should be enough time to get the tubes fully warmed up. Decades ago when audio technology was in its formative stages, recording at home was nothing more than a distant dream.

Musicians would need access to high-end analog equipment, which made recording Their sound quality and convenient design are undeniable, but there are Do preamp tubes need to match? Tube Type Do they need to match?

The three parts are: Grid Cathode Plate The grid in a preamp tube is the input, at which point the low-level signal controls the flow of electrons from the cathode to the plate.

Check out this video that shows how Tube Amps work. The issue with both preamp tubes and power tubes when it comes to matching is that there is so much variation on the market today. Tubes vs. Solid State Amps If you have a solid-state amplifier rather than a valve amp, you will never need to change the preamp tubes or worry about them matching.

Do Preamp Tubes Need to Be Matched?

Preamp tubes are, in the majority of cases, self-biasing. Therefore, they do not require matching. Power tubes are an example of this.

K&K Pure XLR Preamp Mach 2

The result is high-powered clarity that simply cannot be achieved with a regular 9-volt circuit! Electronic circuits work more efficient on higher power and electronic components designed for low power consumption will never sound as good as the more power-hungry components that are optimized for tone quality. Phantom powered preamps, depending on their complexity, also need to compromise on power consumption issues as phantom power fluctuates and diminishes with the number of consumers connected. Generally, low power consumption equals less high-end response, less headroom circuit peaks or overloads sooner , and less overall clarity. This feature alone would make the new Pure XLR Mach 2 Preamp worthwhile, but we added a few more things that players have asked for:. The Pure XLR Mach 2 Preamp preserves harmonics and overtones and provides a more open and true acoustic sound response. We know our customers want the best and truest acoustic tone and we are proud to introduce this new preamp.

Matching speakers and amplifiers: A few essential tips

Having recommended a range of speakers and amplifiers for every turntable set-up, we asked The Ear editor Jason Kennedy to share a few essential tips on how to match them. While most amps and speakers operate on the same principles, when a manufacturer develops an amp or a speaker they make decisions about how it sounds based on the partnering equipment they use. For instance, an amp maker might always use a certain type of speaker in his or her evaluation work, and thus end up with an amp that works best with that type of speaker. This is because power ratings for speakers are an indication of the minimum and maximum power a speaker requires. However, as a general rule you can never have too much power; more power means more control, which in turn means less distortion.
