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Largely superseded by the AZ series (AZ1, AZ11, AZ12).
