Universal size for 12" speakers
Dome diameter: 80 mm - recommended for most of the guitar loudspeaker with average beaming

As the frequency increases, the radiation of a loudspeaker is increasingly focused on its center. If the listener is in this beam, the sound is extremely harsh and biting; if one moves to the side of it, the sound becomes significantly darker and treble components are partially missing.
To reduce this behavior, a diffuser is used. This sits directly in the beam of the speaker and deflects the high frequencies very strongly, it breaks the "beam". This makes the sound much fuller and more balanced.

Speaker Break-In / Agin Service for Guitar Speakers.
Corresponds to a continuous operation of 24 hours.
Many new and unused loudspeakers sound harsh and must be used for a certain time to develop their sound. This ageing process can be accelerates with this service which "wears" different parts of the speaker, so it will sound softer and smoother, in particular the top end.

JJ EL84 #07 - Standard plus

• Slightly hotter than the #06 selection
• Selected and recommended for VOX AC 30 / 15  and similar amps.
• Price for one tube.

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.

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.

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.
