Are you a member of a band wanting to play live venues but still haven’t decided on what amplifier you wish to use?
Save yourself the hassle of browsing endlessly and read on to see what we believe are the best affordable tube amps currently on the market today.
Considerations Choosing good but Cheap Stereo Tube Amplifiers
When deciding on the right tube amp for you, it is always a great idea to consider every facet of your purchase. Things such as the output connection or the signal to noise ratio (SNR) an amp uses can have a massive influence on your chosen amplifier. Nobody want’s a product that dissatisfies in some way. Here are a few things that you should always consider when it comes to finding the perfect tube amp for you.
Typically speaking, the higher the output power (measured in watts, W), the louder your chosen amplifier will be. Although it might be tempting to get the potential loudest amp you can get, you should always consider your living conditions such as whether you are in a block of flats or if your neighbours will be irritated by the loud volume. Most people will be happy with a 10W amp however you may require a much higher wattage, such as 100W if you are planning on using it for live music etc.
Consider the size of your room and proximity from your neighbours before deciding on how powerful an amp you need. A better low wattage amp will be much better than a cheaper high wattage amp for personal listening.
Connections and Inputs
When it comes to considering which connections and inputs are featured on an amp, you should consider every potential connection you may require. Do you plan on using a guitar or keyboard with your amp? If so which connection types do they use?
There are a wide range of connection types that you may require such as a 3.5mm headphone jack or a USB input for external devices. But you should also consider any potential wireless inputs if you plan on using things such as Bluetooth headphones. Making a list of every potential connection type you require and ensuring that your chosen amplifier includes these is a great way of preventing any potential issues further down the line.
One of the more technical terms you may come across, this is a measurement used to compare the volume levels of what you actually want to hear to any potential background noise produced by your amp. Basically, an amp constantly has electrons whirring around inside and if you listen extremely carefully you can sometimes hear them. SN ratio is a useful measurement when it comes to ensuring that the back ground noise of the electronics within your amp does not interfere with what sounds you wish to actually hear.
The big target for any amp manufacturer is to have the highest measurement on the market. The higher the value, the more of your music you will hear and the less electronic interference there will be. It is almost a rule of thumb that the higher the SNR the more you should expect to pay, this however is not always the case as some of the tube amps featured in this article will show you.
Total Harmonic Distortion
Another technical term you will come across when doing your tube amp research is total harmonic distortion (THD). This is a measurement of how of an impact the amplifier itself has on the final sound output. Unlike SNR, the lower the THD figure the better.
A higher THD figure tends to mean the sound output itself will feature more distortion, meaning that it isn’t quite what the original recording sounded like. The lower the THD however, the closer to the original recording the sound output will be. Therefore, it can be ascertained that most people will want the lowest possible THD they can find, unless you want to listen to a distorted version of the original track.
The levels of THD of a tube amp shouldn’t impact the overall price of the amplifier itself but it can be expected that their will be a slight increase in price based upon how low the measurement is.

Do tube amps really sound better?
When it comes to deducing whether or not a particular amp sounds better, most of it comes down to personal taste. However, most people will agree that tube amps sound far better than solid state devices, although arguments could be made against this.
Overall though we would say that tubes offer a unique warmth to their sound output which improves the overall quality of the audio. If it came down to deciding between a solid state amp or a tube amp, we would choose the latter.
Factors to Look for in Tube Amp
Before spending money on tube amps, you must understand what you are buying and its specifications. It is important to remember that solid state amps and tube amps are totally different devices.
While buying electronic items, a general rule of thumb is to first identify usage – whether the product is a long-term or short-term purchase. Once that is decided upon, setting a budget becomes easy, since you know how much you will invest in it. The next thing one should decide is what wattage would best suit your needs. A 100-watt tube amp at its maximum might sound cool, but the noise will be too much for small spaces. A 5-watt tube amp is perfect for use in smaller areas. At its maximum, it will sound amazing, fitting your needs perfectly. Understanding the product specification is also important.
Before selecting a tube amp, you must look into its requirements that’ll help the tube amp produce quality sound. What items you already have, should match the requirements of the tube amp, or you should be able to purchase them separately if need be. One thing to note is that a 100-watt tube amp is not supposed to be twice as loud as a 50-watt tube amp. The only difference between them is 3 decibels and more headroom. The more the watt, the more room it occupies and increases in weight. So, unless you are able to carry the heavy tue amp or have people who’ll do it for you,you’re in for some heavy weight lifting.
The type of tube used in a tube amplifier affects the performance. This should be considered when buying a tube amp. Performance is affected as different types of power tubes have a particular sound based on their characteristics.
EL34: is more gnarly and a nasty sounding tube. It is not distorted but just a little aggressive. It is good for metal rock and is really powerful.
6L6: is completely different than the EL34. It has a cleaner sound and its mids are less powerful and honky. The overall tone is fluid.
6550: is similar to the 6L6. It has some grittiness in its mid-range. It is not very clean but has just the perfect sizzle for hard, dirty tones.
KT88: is based on the 6550. It is more refined and boosted and has less distortion than either the EL34 and the 6L6. It has a super clean sound and clears up the tone very well.
KT66: is the predecessor of the 6L6. KT66 is smoother in higher tones and even in the mids. It is more open sounding and has a better dynamic response.
KT77: sounds somewhere between the 6L6 and the EL34. The sound is a little more compressed than the 6L6 but not as much as the EL34.
6V6: is a smaller tube as compared to others. It gives the tone a sparkle at the top end and a chewiness to the bottom. The 6v6 roars spectacularly if you crank it up.
EL84: is a smaller tube, but gives a grittier, grainier feel to the tone. It lends a slightly dirtier tone to cleaner guitar tones than other amps.
The basics of the power amp are based around the wattage and the tube-type. The power amp is important as it affects the overall output, but the preamp is just as important as it’s the factor that shapes the tone. What should be considered in a preamp is the circuit type and the features it possesses, such as effects loop, reverb or multiple channels. Someone who uses one amp and plays a lot of different tones should consider buying a tube amp with multiple channels. This way, the distortions provided will be under control.
On a guitar amp, there may be anywhere between one to four channels. Tube amps with multiple channels provide users more flexibility to rely less on pedals for overdrive. The user can utilize the independent gain controls for each channel of the tube amps. Most high gain amps have two channels – the clean and gain channels. The user can turn up the preamp gain and leave the master volume set at a lower level, offering greater distortions at lower volume levels.
The preamp tube breaks up sound differently than the power tube.
While multiple channels offer more flexibility, to get more purity in tone, a single channel preamp is better. The tone of your music will be colored through springs in a reverb pan and multiple channels and other components and their settings. So, the more components in the single chain, the more the purity of the tone will alter.
It all comes down to the money There are many budget tube amps in the market that are a run for your money. The main aim is to get a better sound and that is relative. You can get a $4000 tube amp or get a $400 tube amp and they would probably have the same effect. It also depends on the quality of the instrument in use. As with most purchases, the budget decides on what we can buy.
One should see what are their basic use is and how much they can afford to invest. A budget is probably the biggest purchase constraint one can have, another way to ensure that you purchase a tube amp that fits right in your budget is to look at verified online websites that sell them. Many of these sites, like Amazon, have sales that are either based on brands or occasions.
