JJ's version of the ECC81/12AT7 tube type with a warm and soft sound. Often used for phase inverters or reverb drivers.

TT Selection: Balanced Both systems with balanced gain
All JJ gold preamp tubes are selected within a close tolerance and handtested for best sound and quality. Furthermore all pins are gold plated to achieve best electrical contact. What about the sound ? It is still the famouse and well known JJ brownsound - warm and smooth.
TT Selection: V1 - Low Noise This tube is selected for sensitive input stages (V1)
ECC82 / 12AU7 medium gain pre-amplifying double triode. Provides a very smooth sound with well-defined tones suitable for audio and guitar amplifiers. Gold-Version: All JJ preamp tubes are selected within a close tolerance and handtested for best sound and quality. Furthermore all pins are gold plated to achieve best electrical contact. What about the sound ? It is still the famous and well known JJ brownsound - warm and smooth.
Sweet and warm sounding preamp tube with high gain. We recommend this tube for guitar/bass amps.

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.
Remake of a 12AY7 / 6072. Smooth sound, great for fender-like amps.

This tube is recommend to tame the gain of an amp and make it sound "sweeter". The 5751 has only a gain of 70 instead of 100 like the typical 12AX7/ECC83 tube type and can be used as a drop in replacement for 12AX7 / ECC83 tubes.
