Electro-Harmonix's 12AU7 EH (Single)
Tubes by Electro-Harmonix
The choice of vacuum tubes in a tube circuit can make all the difference sonically. We have long experience in “tube rolling”, and access to the finest sounding new and new-old-stock (“NOS”) tubes available. On this website we list only the most popular, mostly new production, vacuum tubes, and also special finds like the amazing 6H23N-EB Russian military tube, which is a drop in replacement for 6DJ8/ 6922/ 7308 types. Please let us know about your actual tube components for a consultation on these listings or NOS tubes.
A premium quality 12AU7 built to match the performance of the military-industrial original GE 6189. Low microphonics and excellent linearity offer a musical and harmonic soundstage, making the 12AU7EH tube equal to the original and a cut above the competition.
