TT Selection: V1 - Low Noise This tube is selected for sensitive input stages (V1) Compared with the JJ 12AX7/ECC83, the JJ ECC83/12AX7 MG has a slightly smoother sound and appears to operate more linearly. It is ideal for low- to medium-gain amplifiers, audio applications, and for taming amplifiers with a very hot voicing. It is also a good alternative to the 5751 and 12AY7.
