Notes
The AZ31 uses a 4V heater (the 'A' prefix in Mullard-Philips convention indicates 4V heater). This distinguishes it from the EZ-series (6.3V) and U-series (100mA series heater) rectifiers.
Brans Vademecum lists equivalents in table IId: 5Y3G/GT, 5Y4G/GT, EZ11, EZ40, EZ41, 6V4, and others — but most differ in heater voltage and/or base type, so they are not drop-in replacements.
CV2862 is the British military designation.
Maximum AC voltage per anode approximately 350V RMS. Maximum DC output current approximately 125mA.
