grundig: 6; Stereo-Automatic-Decoder

In my model, grundig stereo decoder 6, the 470 kohm resistance 
that polarizes the EC 92’s grid is only
270 kohms and the capacitor in series with it results 33 pF 
instead of 18 pF. 

The circuit is original and not tampered 

In Radiomuseum’s photo I saw that the model 
Photographed has values ​​like mine, at least 
resistance. 

Perhaps the change is due to the difficulty of being able 
to cut off the operation of the triode when it receives the 
Carrier stereo?

Thank you

bye
