NOS 6SN7GT JAN CHS VT-231 Sylvania, made in USA
built in the 1940s, blackplate, clear top, D-side-getter, white label, ancor navy logo on base
A fantastic tube. Very sweet and balanced - this is how tubes should sound. I don't know what kind of special souse they used back then. Sound stage is incredible with great, tight bass and transparency that is just like letting fresh air into a room. This appears to be on of the best 6SN7 tubes in existence. This is one of the relics of the past that will not come back and not possible to reproduce.
