Who offers support and assistance with tubes for Audio Valve tube amplifiers?

The high-end manufacturer Audio Valve from Kassel, led by Helmut Becker until his passing in March 2022, set standards worldwide. As a long-standing tube supplier, we know the specific requirements of his innovative circuits, including the famous ABR autobias control, in detail. Whether Challenger, Baldur, the Assistent series, Luminare or Solaris: we know which tubes deliver the best sound. Electro Harmonix and JJ often form the basis, while Genalex Gold Lion or selected NOS tubes such as 6AS7G RSD, PCL805 or QQE03/12 are used for fine tuning.
