The 6SN7GT is a small glass tubular audio double triode. This was a classic design with two separate triodes in the one envelope. The 6SN7 remains the most popular Octal based double triode valve for audio applications. The valve is especially well suited to phase splitter designs.

We have many exhibits from the 6SN7 family in different envelope sizes and with different construction methods. This device uses a miniature pinch as does the Radiotron 6SN7GT

The wide glass tube envelope is 27 mm in diameter and, excluding the IO base pins, is 65 mm tall.
