This 6AS7 Russian 6H13C tube is also known as 6N13S and 6AS7G. These tubes were made in St. Petersburg, Russia by SED and are great sounding alternative to Sovtek 6AS7 tubes. They do not have the Winged "C" logo however.

The 6AS7G tube is best known for being the used in Atma-Sphere OTL Tube amplifiers. The Music Amplifier MA-3 uses 42 6AS7 tubes per channel!

The 6AS7-G tube is also a nice choice for many OTL headphone amps such as the Woo Audio 2, 3, and 22 models.

Very nice power tube for the Woo Audio WA-3.


Very "clean" sound on the Woo Audio WA-3. Low end was was punchy, but not thick. Both triodes were balanced nicely and there was no real apparent difference in performance after the short break-in period. Physically, the tube was clean and in excellent shape; no marks or scratches on glass. I will have to get a couple more, at this price, as backups...
