I have two brand new, never used tubes (spares) left over from my Atma-Sphere amp days.
The Russian 6H13C tube is also known as 6N13S and 6AS7G. These tubes were made in Russia
and are great sounding alternative to Sovtek 6AS7 tubes. The 6AS7G tube is best known for being the used in Atma-Sphere OTL Tube amplifiers, AR and many others.
$45 for the pair, including ground shipping to lower US.
