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.

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.

FAQ: If I order two or more of these tubes, are they all "the same"?
Yes, the tubes are all "matched" and selected for the in the description mentioned amplifiers.
FAQ: Can I replace the tubes myself or are adjustments needed?
Adjustments are not possible on the listed amplifier (unless a bias potentiometer has been added afterwards). The replacement can therefore be done without adjustments.
