New Gain Tested Tung-Sol Reissue 6SN7GTB Vacuum Tube 6SN7 6SN7GT

The 6SN7GTB is the low noise version of the 6SN7, 6SN7GTA, and 6SN7GT. They are all compatible. This is one of the only New Production 6SN7's available and given how musical and warm it sounds, I'm not sure we need any others as long as they keep making this one!
