Designed for power supply rectification in AC radio receivers. Introduced in 1932 as successor to the RGN1054, later superseded by the AZ1 in 1935. The designation follows Telefunken's naming convention: RGN = Richtergleichröhre (rectifier tube).","is_directly_heated":true,"completeness":"high","notes":["Directly heated cathode with 4V/1A filament.","Dual-anode full-wave rectifier rated for 2x 500V at 60 mA or 2x 300V at 100 mA.","Maximum Ua x Ia product is 30,000 within the 300-500V range.","15 identical replacement types exist per Radiomuseum including types from multiple European manufacturers.","Produced from 1932, superseded by the AZ1 in 1935.","European B4 base (4-pin) with directly heated cathode — filament connects to center tap of HV transformer secondary.","Peak Inverse Voltage is not explicitly stated in the Telefunken/Valvo RGN1064 datasheet; PIV=1414 V is derived from the standard full-wave capacitor-input relation PIV = 2 × √2 × Va_max (500 Vrms).
