DLL 22T

The quite rare PA valve

of the

German

Spy-set

SE 109/3

                                                                                                           Staritz Abwehrfunk-Funkabwehr

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

The pentode grids are well visible

The most outside grids constitute G₃ or suppressor grid

Viewing it from a different angle

I suppose that 5 points at production information 

Maybe of some interest is my CHiDE contribution of 2003:
