12AT7 / ECC81

12AT7 / ECC81 Tubes

12AT7 is a dual triode often used as drivers. For use in phase inverter position, we recommend triode matched option. For reverb driver, we recommend smaller plate 12AT7 such as Electro-Harmonix 12AT7EH-WC. We also offer low noise option to eliminate potential issues. Reverb drivers dissipate lots of power and wears out faster, so we recommend carrying spare as well.

All our 12AT7 tubes can replace any 12AT7, ECC81 tube types.
