12AT7 / ECC81

12AT7 from BOI AudioWorks 12AT7 tubes listed here can replace any 12AT7, ECC81 tube types.

For use in phase inverter position, we recommend Triode Matched tubes.

For Reverb driver, use low microphonic tubes like Electro-Harmonix 12AT7WCEH. Reverb drivers tend to wear quickly, so keep a spare handy.

Check out our matching or noise screening options.
