Sensibly equivalent¶ to:
This exhibit is an American made glass 6H6 double diode. The construction uses a small pinch and whilst being a small valve is much larger than the earlier all metal, and original, metal 6H6.
The diodes are low voltage low current signal rectifiers and not suitable for power supply service. The low current is reflected in the low heater power.
The wide glass tube envelope is 28 mm in diameter and excluding the IO base pins the valve is 53 mm long.
