Groove Tubes: GT-12AX7-M

   


 

The new GT-12AX7-M is a reissue of the original Mullard 12AX7/ECC83 dual triode preamp tube.

This tube delivers rich, harmonically complex tone and midrange warmth that is just not available
in any other currently manufactured tube today.
Its unique triple mica design reduces tube hum and microphonics.
NOS tubes (New Old Stock) are hardly available today, but if you have found some good ones

consider yourself  very lucky. Our experience is that, after paying way too much for what

possible is a used 'NOS', they also DON'T seem to be the first choice in V1-inputstages of

preamps and certainly not in poweramps because of hum, hiss and crackling noise after a while.

After testing all possible brands 12ax7s we could get our hands on, we at GtrGear rate the

GT-12AX7-C and GT-12AX7-M as the best production 12ax7 currently available. (GtrGear)

Note: there are no adjustments needed. Dropping in this tube takes less than 10 seconds!
