• Notes
• Variante für Wechselstromspeisung 125 V (Spanien). Vermutlich Kleinserie wegen kriegsbedingter Nichtverfügbarkeit der UCL11 umgerüstet auf ECL11. Zusätzlicher Autotrafo für die 6,3 V Heizspannung der ECL11 sowie zur Transformation der 125 V Netzspannung auf 220 V für die Anodenspannung. Die übrigen (U...) Röhren laufen in Serie auf 125 V.
  Siehe auch Tefag K5A für 220 V Allstrom-Betrieb.
  
  Variant adapted for 125 V (Spain). UCL11 tube substituted by ECL11, obviously due to material shortage (UCL11) during WW2.
  Transformer added to standard model. Primary acts as autotransformer to convert from 125V to 220V. Secondary gives 6.3V for ECL11 filament. Rest of filaments connected in series to 125V.
