12AT7 / ECC81

12AT7 tube is a dual-triode often used to drive output tubes or reverb tank. 12AT7 tube is similar to 12AX7 but with lower gain and more current capability.
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, 6201, and CV4024 tubes types.
