The 6SN7GT is a small glass tubular audio double triode, the design dates to the 1940's. This was a classic valve 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.
The 12SN7GT is identical operationally but has a 12.6 Volt heater.
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.
