The B36 is an audio double triode with a 12.6 Volt heater. It is a British (M-OV) copy of the American 12SN7.
The construction uses a glass pinch and two separate electrode structures are visible within the glass.
The B36 was designed for audio applications and the valve has independent cathodes. The B65 differs only in heater voltage and current.
The wide glass tube envelope is 28 mm in diameter and excluding the IO base pin length, stands 71 mm high.
References: Data-sheet & 1040. Type B36 was first introduced in 1948.
