Sensibly equivalent¶ to:
The BVA132 is a battery double diode triode that has a very low filament consumption. It would have been used for detection, AGC detection and first audio amplification in radio receivers specifically the civilian receivers made during WWII in the UK.
The reverse of the envelope is plain zinc paint.
The classic envelope is 32 mm in diameter and, excluding the MO base pins, is 81 mm tall.
