12AX7 / ECC83 Tube Types

The 12AX7 (ECC83) vacuum tube was invented almost 70 years ago and is still an absolute necessity for every electric guitar tube amp and a wide range of hifi audio tube amplifiers. Another common name for the 12AX7 tube is ECC83 and for premium versions the 7025 and ECC803 audio tubes. Originally, the 12AX7 / ECC83 vacuum tube was introduced to be a superior option for lower noise and microphonics over the 6SL7 tube that was commonly used in the 1940s. As well it offered more gain. Today, a look at almost any guitar tube amp, be it Fender, Marshall, Vox, or any other, will prove the 12AX7 / ECC83 / 7025 tubes are here to stay.
