This DAC32 exhibit is covered in the Mullard red external metallisation. The DAC32 is a dry battery diode triode that was designed, after WWII, for AM broadcast radio reception. Mullard describe this valve as a medium gain triode for use as an AF voltage amplifier combined with a single diode for signal or AVC (AGC) rectification.
The filament power is very low and consequently the valve is rated for a very low current.
See also DAC32 for a clear envelope version.
The wide glass tube envelope is 30 mm in diameter and excluding the IO base pins it is 86 mm tall.
