The CV753 is a miniature diode on a B7G base and features a 1.4 Volt indirectly heated cathode. The prototype was the 1A3 and both Type designations appear on the glass.
The diode: the insulated heater is a single vertical strand within the cathode cylinder. The anode has side fins to anchor the anode and to provide heat dissipation. The working area is small.The thin glass tube envelope is 18 mm in diameter and, excluding the B7G base pins, is 47 mm tall.Reference: Data-sheet. Type CV753 was first introduced in 1943.
