Do tube preamps sound better?
As a tube creates distortion it produces harmonics which are known as ‘even harmonics’. Essentially these are tones which are the same note but are produced higher in octaves. This is why typically a tube amplifier is said to sound better, because the harmonics it produces are much more pleasing to the user’s ear.
Can you use a tube preamp with a tube amp?
Most tube amplifiers have an input impedance of at least 100K Ohms, so they are compatible with most any tube preamp. Most solid state amps have an input impedance of 50K ohms, so the output impedance of the preamp should be 5,000 ohms or less.
What is the difference between preamp and poweramp?
A preamp boosts a weaker signal, bringing it to line level, and a power amp boosts the line level signal before it goes to the speakers. In other words, a preamp increases signal strength to an acceptable level to transmit to the equipment in your chain.
Can I use power amp without preamp?
Entirely possible. A pre does two things. One, bring the voltage (and impedance) of the input source to a level where the power amp can deal with it easily.
Are Ruby 12AX7 tubes good?
The Ruby 12AX7AC5 High Grade Preamp Tube is an extremely popular 12AX7A tube and our best seller here at Eastgate Music. It’s Ruby Tubes highest quality 12AX7’s! All Ruby pre-amp tubes are properly tested for quality assurance.
Why do tube amps sound better than solid-state?
Are Tube Amps Better Than Solid State? Tube overdrive is much smoother and more responsive than solid-state. It can be influenced by adding high-gain pedals to the signal chain between the guitar and amplifier, and this gives players much more control over the sound.
Do 12AX7 need to be matched?
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.
What is the difference between 12AX7 and 12AT7?
Main Differences Between 12AX7 vs 12AT7 Tubes
The main differences between 12AX7 vs 12AT7 are: The 12AX7 has a gain output of 100, whereas the 12AT7 has a gain output of 60. The 12AX7’s high gain can make it prone to clipping and distortion, whereas the 12AT7 can give you more headroom.
Which is more important preamp or poweramp?
Power output could be a big concern with power amps depending on your speakers and environment. Power output is never a concern with preamps, though gain might be. The poweramp is typically going to be a bigger safety concern for your speakers than the preamp.
How do you match a preamp to a power amp?
How to match a preamp to a power amp – YouTube
Is preamp really necessary?
Bottom line: An external preamp is a great second step to improve your sound quality or to obtain more sound variety, but don’t make the second step before you’ve made the first. You can make great recordings with just your audio interface’s internal preamps and one or two high quality condenser mics.
Where are JJ tubes made?
Slovakia

How long can tube amps be left on?
How long can you leave a tube amp on? A tube amp is designed to be on for long periods of time. This, however, is not a recommendation. Most manufacturers will recommend no more than 6 to 8 hours of continuous play with at least a 30-minute cool-down break.
How long should you warm up a tube amp?
20 to 30 minutes
As a rule of thumb, your tube amp needs to be warmed up for 20 to 30 minutes at least before you can start playing your guitar. Most of the time, tube amps have warm up specifications included in their instructions for use.
How long do 12AX7 tubes last?
about 10,000 hours
Small signal tubes like a 12AX7 or 6922 will work well on average for about 10,000 hours.
How often should you change your preamp tubes?
2 – 3 years
Preamp Tubes are generally at their best 2 – 3 years. Power Tubes are generally at their best 1 – 1.5 years. Rectifier Tubes are generally at their best 3 – 5+ years.

Can I replace 12AX7 with 12AT7?
You can interchange a 12AX7 with 12AT7, 12AU7, 12AY7 or 5751 as they are all the same pin structure, however they will each give you a different result in your amp. Each of these tubes has a different gain factor, which means some will give higher gain and others lower gain.
Why use a preamp and a power amp?
A preamplifier will boost voltage gain, but not current gain – that’s where your power amplifier comes in. Keeping the power amplification separate from the more delicate circuitry of the preamplifier is one of the ways of keeping noise and interference out of your signal.
How do I choose a preamp?
Choose your phono preamp according to the sound quality required. Depending on the type of music you play and naturally the sound quality you are looking for, you will have to consider different phono stages. Sound quality will differ depending on the components used by the manufacturers, and the technological bias.
Does preamp improve sound?
The sound contribution of preamps is not so much in its frequency response but in the texture it imparts on the sound. However, a preamp shapes the sound to a much lesser degree than one would think. Usually, its sound character only becomes obvious at high gain settings or when you drive it into distortion.
Does a preamp boost volume?
Here’s where preamps come in: preamps allow us to amplify a quiet, mic-level signal up to a louder (i.e., higher voltage) line-level signal. The rest of the equipment in our chain, like additional outboard gear and analog-to-digital converters, expects a line-level signal for optimal volume and signal-to-noise ratio.
Why are vacuum tubes no longer used?
In the 1950s, the invention of the transistor started to replace the vacuum tube, as vacuum tubes were larger, fragile like a light bulb, and expensive. As computing devices started to become smaller in size, transistors were more ideal to use due to their smaller size.
Are tube amps going away?
ALL tube amp manufacturers are now unable to meet production schedules for any of their tube models and insiders are saying that Fender is cutting production in half and that cuts will go deeper soon. You can’t find a tube out there from the normal suppliers any longer… everything is out of stock.
