Can I replace ECC83 with 12AX7?

Can I replace ECC83 with 12AX7?

Some people might worry about whether or not you can substitute the ECC83 for a 12Ax7, and many guitar shops will only carry one brand of preamp tube. If that brand is an ECC83 tube, you might be hesitant to make a purchase, but you needn’t be. The ECC83 tube will perform the same as the 12Ax7.

What vacuum tubes are interchangeable?

Normally equivalent vacuum tubes such as a 6J5 or 6J5GT or 6J5G are electronically the same. They may have a different construction, i.e. metal versus glass, or a different glass shape. They will perform the same.

Is ECC83 tube same as 12AX7?

The 12AX7 Valve (or 12AX7 vacuum Tube) is a small preamplifier valve which is identical to the ECC83 – same valve, just a different name. It has two identical triodes both of which have a high voltage gain. In fact, it is one of the few small-signal vacuum tubes in continuous production since it was introduced.

Which vacuum tubes are valuable?

Sought after by Audiophiles, these include the common U.S. made 6L6 ($15-$25) and 12AX7 ($8-$15). If it’s a Telefunken brand you can easily double or even triple the price. Some newer Western Electric tubes are also sought after by Audiophiles for use in amplifiers and vintage stereos.

What does GT mean on a vacuum tube?

“G” means a glass version of a metal octal tube, typically in a larger bulb with shoulders. “GT” means a glass tubular version of a metal octal tube.

What kind of valve does an ECC83 use?

The ECC83 (12AX7) valve is used in the preamplifier section of 99% of all valve guitar amplifiers. Usually there are between 2 and 5 of these valves in the preamplifier section. They all do the same thing which is to amplify a smaller signal into a larger one.

What’s the difference between a 12AX7 and an ECC83?

The truth is, there is no difference at all between them, and each one is interchangeable with the other. 12Ax7 (Fig 1) is merely the American name of the tube. ECC83 (Fig 2) is how it’s commonly known in Europe, and it is also its Mullard-Phillips tube designation. There are also many slightly altered versions of these tubes.

Is the 7025 the same as the ECC83?

Because the 7025 (ECC83) has a lowish current capability, you can’t use it to drive the speakers. For that, you need bigger, beefier power valves. The 7025 (EXCC83) is confined to the early stages of your amplifier where it boosts low-level signals to useable levels.

What is the amplification factor of the ECC83?

The ECC83 high impedance amplifier triode was designed specifically for audio use and has a high amplification factor of 100. Mullard describe the ECC83 as a high μ double triode, having separate cathodes, primarily intended for use as a resistance-coupled amplifier or phase inverter.
