The Genalex Gold Lion 12AX7/ECC83 features a tight, powerful, yet balanced sound. Ideal where punch, stability and low noise are required.

Originally made by Marconi-Osram Valve Co. (Genalex) in England, the famed 12AX7/ECC83 power tube is once again available. The Russian made reissue of the Genalex Gold Lion 12AX7 uses premium manufacturing materials such as gold plated grid wire and carbonized plate structures. The glass bottle and spacers have been engineered to reduce noise and microphonics.

After extensive research and engineering, New Sensor Corp. has reissued the famed Genalex Gold Lion audio vacuum tubes. The ECC83/B759, ECC82/B749, ECC81/B739, and E88CC/6922 preamp tubes are outstanding in both hifi tube audio amplifiers and electric guitar tube amps. Many of our customers have found the ECC83/B759 tube exceptional in tube phono stage preamps.  They are also excellent in Marshall styled guitar amps where gain is important without sacrificing tone. We should mention that these European part numbers are often better known by different names.  The ECC83 is equivalent to the 12AX7 tube.  The ECC82 tube is equivalent to the 12AU7 tube.  The ECC81 tube is equivalent to the 12AT7 tube. The E88CC tube is equivalent to the 6922 tube.

The power tubes by Genalex/Gold Lion are great as well.  Consider the Genalex KT88, KT77, KT66 and 300B tubes when looking for premium audio vacuum tubes for use in high end tube audio amplifiers.  The Genalex / Gold Lion KT88 has long been a top-seller.  As well the Genalex / Gold Lion KT66 tube is the top pick for customers who wish to upgrade their vintage and reissue Marshall JTM45 and Bluesbreaker tube amps.
