The quite rare PA valve
German spy-set type 109/3
Albeit that the PA valve isn't visible from outside.
The English text was used as to fake the ordinary people; as one expected German language information on German sets.
The schematic of the type 109/3 spy-set
The DLL 22T is clearly electrically shown on the right-hand side.
It is evident that both pentode sections being connected in parallel, effecting in an increased output power of 3 watt.
The type number DLL 22T on top
