Description

Miniature type used in light-weight, compact, portable, battery-operated receivers as combined detector and voltage amplifier. Filament 1.4 volts, 0.05 amperes.

The 1S5 has the same electrical characteristics but the 1U5 uses an improved structure which greatly reduces any tendency toward microphonic effects. In addition, the diode unit is effectively shielded from the pentode unit to prevent "play-through". They are not interchangeable since pin allocation is completely different.

Guten Tag ,

Ich hätte eine kleine Bemerkung zur Batterieröhre 1U5 zu machen :

 

Die amerik.Batterie-Röhre 1U5 entspricht der europ.Type DAF92 und wird hier in der Abbildung

mit der richtigen Sockelschaltung (Belegung) dargestellt.

Die Röhre wäre auch austauschbar mit den ählichen Typen 1S5 (DAF91) wie in der

Beschreibung erwähnt wird ,aber nur indirekt ,denn die Sockelbelegung der 1S5 ist eine Andere !

Die zur Hilfe ,damit eventuelle Missverständnisse bei Röhrentausch  ausgeräumt sind  .DieSockelbelegung derDAF 91 / 1S5 findet man unter der Beschreibung dieses Types.
