The 6SL7GT is a medium impedance double triode with a modest gain. It was probably a general purpose valve.
The twin triodes each have a folded plate anode sealed to the support with a flange for greater heat dissipation.
Seen from the back the locking hooks in the anode plates can be seen.
The wide glass tube envelope is 28 mm in diameter and, excluding the IO base pins, is 62 mm tall.
