The Sovtek 12AX7WA is a defacto standard in 12AX7 tubes for many years yet because of its high dependability and its low noise floor.

With a soft and detailed sound, as well as sufficient headroom, the TT 12AU7/ECC82 enhances the sound characteristics of any amplifier, whether it's for guitar, bass, or high-end. These tubes deliver a dynamic range, captivating listeners and musician with uncompromising clean sounds and rich overdrive.

Features:

• Detailed sound
• Ideal for both low and high gain amplifiers

Tip:
Often, 12AU7 and 12AT7 types are used instead of 12AX7 tubes to either reduce the overall power of the amplifier or to just reduce the overloading of the preamp. In comparison to a 12AX7, the 12AU7 brings about a very large sonic difference, typically much greater than switching from 12AX7 to 5751 or 12AT7.

When using a 12AU7 in a driver stage normally designed for 12AX7, the overall power of the power stage is usually reduced. The extent of this difference depends on the amplifier or circuit. For example, a Marshall amplifier with a 12AX7 in the PI stage set at volume 5 will then reach the same volume level with a 12AU7 at volume 6 (perceived volume, not measured).

NP2X-BAG

The heavy duty professional phone plug series improves on the design of the existing C series by offering the thinnest available A-gauge 1/4" plug with unique Neutrik chuck type strain relief on the market. The slimline shell with a width of 14.5 mm meets the most recent requirements for highest density jackfields (15.88mm jack pitch). The precise machined one-piece tip contact without rivets makes it unique and avoids hook up in a socket or break off the tip. The Plug X Series serves all applications such as guitar applications, audio cables, snakes, speakers, amplifiers and mixing desks.
