Tung Sol 12AX7 Preamp Tube

The Tung Sol 12AX7 is warm and big musically. Very consistently made tube. High gain, super low microphonics, and superb linearity with a three dimensional tone. For more clean headroom in your amp, order this tube with the low gain option at no extra cost.(Similar to a 5751 in gain). Avoid these in high voltage cathode follower (CF)spots.
