Electro-Harmonix's 12AX7 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.
The 12AX7 Gold Pin is the Gold Plated version which offers a substantially better contact with the socket. The 12AX7EH provides high gain with ultra low noise and a detailed - musical tone that rivals the most desirable NOS types. Unique spiral filament eliminates that filament-to-cathode induced hum common on AC-powered amps. This tube can be used in phase inverters / preamp sections / driver sections - It really does well in all applications.
