Notes
Early Telefunken full-wave rectifier from the 1930s. Directly-heated cathode despite the 'G' in the designation. The RGN naming convention: R=Gleichrichterroehre (rectifier), G=indirekte Heizung, N=Netzanschluss. 4 V filament for European mains receiver transformer use. Largely superseded by the AZ series (AZ1, AZ11, AZ12). Pin Layout — B4
