Electro-Harmonix 12AT7

Electro-Harmonix 12AT7 is an excellent upgrade for HiFi audio applications.

Electro-Harmonix 12AT7 features a long-plate design that has fuller sonics. Electro-Harmonix 12AT7 works well in low gain applications such as phase inverter.

Due to the long plates, however, it can be more prone to microphonics.

For reverb driver and other application where microphonic noise matters, we recommend TungSol 12AT7 or Electro-Harmonix 12AT7WC
