| Description |
Amateur Transmitting tube by DeForest.
Ua= 700-3000 V; Ia= 110 mA; -Ug= 50 V; Power 250 W.
It is not clear if it is the type H (H_DeForest), since data are considerably different:
250 W / 150 W; 110 mA / 50 mA (Tyne: up to 100 mA); Filament 2,75 A / 2,35 A.
More powerful variant? Based on Test results? Copy error?
Anyway it is improbable that 'Senderöhre' was the actual name given by De Forest to one of his tubes. Please refer to H_DeForest.
