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.

JJ 12AX7 MG / ECC 83 MG with gold plated pins.

The newest member in the JJ family of ECC83/12AX7 tubes is the JJ ECC83MG. The MG is a 12AX7 with a bit lower amplification than a standard 12AX7. Our measurements show that the difference is small, but the new tube sounds more linear than the standard JJ 12AX7, and in amps produces a milder, gentler sound. The mechanical construction shows that it is not just another minor variation of the normal JJ 12AX7. The new tube has longer plates. The JJ ECC83MG is interesting for low and medium gain amplifiers, as well as for audio, where a too hot amp needs to be tamed; as well as an alternative to a 12AY7.
