The VX7076 is the prototype for the 6AL5 miniature all glass double signal diode.
These diodes were specifically designed for vision and sound detection in television receivers. Additionally they are recommended for limiting and DC restoration.
The characteristic structure of the 6AL5 with two bright diodes separated by a screen.
The anode fixed into the supporting mica disc with tabs. The heater is a double helix to cancel the AC magnetic fields.
The thin glass tube envelope is 18 mm in diameter and, excluding the B7G base pins, is 45 mm tall.
