Notes
The 'N' suffix indicates a revised/improved version of the AZ11.
For characteristics and curves of the AZ11, see AZ1 (per Philips datasheet).
Full-wave rectifier — two anodes, common cathode.
4 V heater, indirect heating.
Valve_Equivalents lists this as 'Double Diode' on G8A base.
Peak Inverse Voltage is not explicitly stated in the Telefunken AZ11N datasheet; PIV=990 V is derived from the standard full-wave capacitor-input relation PIV = 2 × √2 × Va_max (350 Vrms). Matches the convention used for AZ12, UU4, UU5, EZ41 in this repo.
Vdrop=20 V is read from the AZ1 single-plate I/V characteristic (Philips datasheet Abb. 3, Ia per anode vs Va — AZ11N shares the AZ1 curve per Philips handbook note 'For characteristics and curves of the AZ11, see AZ1') at 32.5 mA per plate (= Idc_max 65 mA / 2 for full-wave). The datasheet does not state a discrete Vdrop value.
