12AT7 / ECC81

12AT7 / ECC81 Tubes

12AT7 is a dual triode often used to drive output tubes or reverb tank.
For use as an output driver (phase inverter), we recommend the triode matched option. For reverb-driver use, we recommend small plate 12AT7 such as Electro-Harmonix 12AT7EH-WC or TungSol 12AT7.

Reverb drivers dissipate lots of power and wear out faster, so we recommend carrying spares.

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