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.
