Psvane WE KT66 GC - Matched Pair | Λυχνίες Τελικές Ζεύγος, Ματσαρισμένες

The PSVANE WEKT66GC.2  get shipped as factory matched pair

Psvane WEKT66GC correspond to the electrical specifications of the original Genalex Gold Lion from England in the 1960s.

The historic Gold Lion, manufactured by Marconi-Osram "MO-Valve", was also available with grey-coated glass on the inside. This serves on the one hand for shielding and on the other hand for better heat dissipation and thus for a more stable operation in the long term.

 

The KT66 tube is referred by audiophile as Super-6L6GC due to its silky sound.

 

a timeless beauty in perfect build quality for years of your audio performance
