This 12AX7/ECC83 is a new production copy of the famous Mullard 12AX7. This tube has a higher gain presence than most other 12AX7's. Low noise and very low microphonics makes this a great preamp tube for your amplifier.

These are new production by New Sensor. We were shocked at how good these re-issues are. Try them in your classic guitar amplifier as well, for that thick 60s sound with fast attack and decay. Does it approach the original Mullard in sound?.
