6SN7 is a dual triode vacuum tube with an eight-pin octal base. It provides a medium gain (20 dB). The 6SN7 is basically two 6J5 triodes in one envelope. The 6SN7 was originally released in 1939.

But the 6SN7GT is arguably the best general-purpose audio triode. Its large octal format is more rugged and less prone to intermittent pin connections than miniature type. Its mu of 20 is a nice compromise between the old low-mu types and low-current high mu types. The plate resistance is low enough to drive choke or transformer loads.
