NOS Tung-Sol 6SN7GTB Preamp Tube
The New Old Stock/NOS Tung-Sol 6SN7GTB vacuum tube is a fantastic preamp tube or driver tube. These are tall-bottle versions with black plates. It's difficult to date them precisely but late 50's to ‘60s era production. Many in original boxes but unfortunately a lot of them have boxes that didn't hold up all these years and we've had to re-box them.
Known to be well balanced and low-noise. Many audiophiles describe these vintage 6SN7 tubes as smoother, less “harsh” and more detailed than the modern reissues.
