Extras ▼

 

The EBC81 is a double diode triode with the triode designed for audio amplification. The diodes share the same cathode as the triode and would be used for signal detection and AGC rectification.
The grid winding on the copper rods can be seen through the hole in the mesh screen.
The thin glass tube envelope is 20 mm in diameter, and excluding the B9A base pins is 52 mm tall.
References: Datasheet & 1040. Type EBC81 was first introduced in 1954.
