Are 12AX7 and 12AT7 interchangeable?

Are 12AX7 and 12AT7 interchangeable?

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.

What does high gain tube mean?

A higher gain or stonger tube will only add more distortion down the line in that amplifier. It would probably work best to set the amplifier up cleaner and use a pedal or something up front to get added gain and distortion. Or setup for a little extra distortion and back off of the volume up front for cleaner tones.

How do I reduce the gain in my tube amp?

Using resistors before the volume is most likely the best way to reduce gain.

What is a cascading gain stage?

Cascading multistage gain structures are found in the preamp sections of high gain tube amps. In contrast to single stage circuits, they create gain and clipping by connecting several lower gain stages in series with each other.

How do high gain amps work?

In amps of this type, the saturated overdrive sound we hear is typically produced by pushing early gain stages to very high levels, often chaining one into the other to continually drive the gain higher and enable desired levels of distortion, and then reining in the signal at the end of the line to create the desired …

Which is the lowest gain 12AX7 or 12AT7?

The 12AU7 has the lowest gain of these three, with an amplification factor of 20. This is used much less as a preamp tube and more often as a driver for spring reverb.

What is the gain factor of a 12AX7 tube?

The gain factor of a tube simply measures how much it amplifies the input signal. For example, the common 12AX7 tube has a gain factor of 100, while a 5751 tube (which is often used in place of a 12AX7) has a gain factor of 70. This means that if you plug a 5751 into a socket that expects a 12AX7, the pre-amp will have about 30% less gain.

Which is better a 12AT7 or a 12AY7?

It depends on a lot of things.Gain is just the start. A 12AT7 will work but a good 12AY7 will be best. That’s not true.A different tube can easily sound ‘thin’ or ‘brighter’ than another tube,even the same type.Example:a JJ 12AX7 is darker than an EH 12AX7 by a long shot.Usually a lower gain tube is darker than a higher gain tube for the most part.

What’s the difference between a 12AX7 and a 12AU7?

The biggest difference between these power tubes is the amount of gain they will provide. The 12AX7 has a gain factor of 100, while the 12AT7 has 60. The 12AU7 has the smallest, at just 20. The lower gain of the 12AT7 and 12AU7 also allows them to have a higher headroom, which can provide a warmer and cleaner sound.
