TT Selection: V1 - Low Noise
This tube is selected for sensitive input stages (V1)

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.

Very linear working 12AX7 / ECC83 with long anode plates and spiral heating, which makes the tube less sensitive to interference from AC heating.
We recommend this tube for audio and high-end amps as well as for "modern" Fender amps with more overdrive, but also as an input tube in old Marshall JCM800s.


Note: Tubes equipped with long plates are commonly associated with a "warmer" or "richer" sound, whereas those with shorter plates tend to deliver a "tighter sound". However, tubes featuring long plates exhibit increased sensitivity to vibrations and mechanical disturbances, rendering them less ideal for critical applications.

Sonically similar to the "normal" JJ 12AX7, but the overall sound is "fuller" and "stronger" with a more powerful bass. Visually, compared to the normal JJ 12AX7, the long anode plates stand out, as well as a slightly higher current. Suits well in guitar and bass amps, but also in audio and high-end areas.

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 famous and well known JJ brownsound - warm and smooth.
