Description
NN095-Electro Harmonix 12AX7 / ECC83
Vacuum tube 12AX7ЕН, 12AX7SV is a miniature twin triode with equipotential cathodes, designed to amplify low frequency voltage in radio engineering devices. Top choice for gutiar / bass amp application with all the right ingredients. Excellent tonal bal-ance, harmonic content, low noise floor, and low microphonics. The tone is more vintage sounding, and also does very well in audiophile application. The 12AX7-EH tube has a nice balanced sound, a very low noise floor and excellent perfor-mance in terms of microphonics. The lack of microphonics is due in part to the return of a shorter plate structure and better materials.

GROOVE TUBES GT 12AT7 PREAMP TUBE
The Groove Tubes GT-12AT7 preamp tube is manufactured to the highest quality JAN spec. NOS, made in Russia for extremely long life.
Used widely in most U.S.-made amps and, in particular, Fender amps. Fender amps with reverb use 2 - 12AT7s -- one for the reverb drive stage, and one as a phase inverter to drive the push/pull output stage. The makeup of the 12AT7 is very similar to the 12AX7 and it can be substituted for a 12AX7 in a pinch. Some players prefer the 12AT7 in the driver stage of a Marshall for a cleaner, brighter tone. (The driver or phase inverter is the 12AX7 located nearest the power tubes.) The 12AT7 is rarely used in a tone-generating stage, but rather in function stages, so the Groove Tubes GT-12AT7 is selected for durability.
