Genalex Gold Lion Tube 12AT7 / ECC81 / B739 Gold Pins

The high-end Genalex Gold Lion Gold Pins double triode tube unveils a wide sound stage, characterized by expressive midrange, deep and precise bass and generously developed treble. This re-release of the Genalex Gold Lion ECC81 / B739 faithfully recreates the sound signature of the original, considered the best 12AT7 tube ever designed.

The contacts of this tube are gold plated, allowing a very good conductivity and resistance to oxidation.

Belle amélioration
Il remplace avantageusement une EH qui équipait mon ampli casque Canor tp10: aigu plus suave, médium plus souple et champ sonore mieux ressenti avec mon Grado PS500E.
