The 6BX7GT double triode was designed for use in 525 line television receivers as frame oscillator and amplifier. Consequently it is built to withstand high peak voltages and also a high cathode current.
Haltron were resellers not the original maker.
Although not imagined at the time of original manufacture, the 6BX7GT has been used as an audio amplifier.

The wide glass tube envelope is 28 mm in diameter and, excluding the IO base pins, is 70 mm tall.
Reference: Data-sheet. Type 6BX7GT was first introduced in 1952.
