A great choice for a phase inverter tube.

The Groove Tubes GT-12AX7-R2 Preamp Tube is the second offering from the Russian tube factory. It has larger plates and a big bass response, also a spiral filament which reduces hum in some amp designs.

These long plate tubes are a great choice for a phase inverter tube as well for fans of long plate phase inverters.

A Groovy preamp tube!

By Shred Fest

from Grand Rapids MI

Comments about Groove Tubes GT-12AX7-R2 Preamp Tube:

I play through a Dual Rec and have tried a few different brands of preamp tubes throughout the years. These tubes work great! I have over 10 hrs on these tubes now and I have only heard good things while using them. I have noticed less hum noise and better bass response. These tubes are more expensive but if tone is a priority then you can't go wrong with this purchase.
