The CV876 (commercially the 7A6) is a loctal based double diode for use in superhet receivers for signal and AGC circuits.
The electrical characteristics are similar to the 6H6 IO based double diode.
The gettering covers the whole inside of the envelope. The guide pip can be seen on the skirt together with the key on the spigot.
The wide glass tube envelope is 29 mm in diameter, and excluding the B8B base pins is 55 mm tall.
