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

Nel mio modello di grundig stereo decoder 6 la resistenza da 470 kohm che polarizza la griglia della EC 92 risulta da 270 kohm ed il condensatore in serie ad essa da 33 pF invece che da 18 pF.

Il circuito è originale e non manomesso

Nella foto in radiomuseum ho visto che anche lì il modello fotografato ha i valori come i miei, perlomeno la resistenza.

Forse il cambiamento è dovuto alla difficoltà di riuscire ad interdire il funzionamento del triodo quando riceve la portante stereo?

Grazie

Giorgio Gelsomini

Hello from the U.S. of A.!

This is my first post, so I hope I'm doing it right! I am proud to be a member of such a valuable organization and am looking forward to a long and mutually rewarding relationship.

I am in need of an English translation of the alignment instructions of the Grundig Stereo Decoder 6. I have schematic and instructions in German only. I have necessary test equipment except stereo generator.

Any assistance will be much appreciated!

  2 Dear Gary,

I would like to help you, at least regarding the translation. My information about the decoder 6 descend from a small book, entitled "Stereo-Decoder -  Funktion und Schaltungstechnik", author Ludwig Ratheiser, published in 1968 by Franzis Verlag München. Ratheiser describes function and alignment.
But in his instructions he refers to the SC1-stereocoder, and without such equipment it will be impossible to get a satisfactory result. Is ist possible for you to rent or buy a coder ?

Best regards
Rolf

Hello Rolf,

Thanks for your reply. I will look for a stereo generator. Perhaps I can find one on eBay.

Regards,

Gary

  4 In the meantime, I have tried to translate the alignment instructions, You find them as a PDF-file in the attachment below. But it seems, You have to get hands on a Stereo coder, to perform the aligment procedure correctly,

Hello for everybody,

I had work in Grundig KS740 with a decoder.

I upload to Rmorg a decoder diagram, is possible to download from  Mod.-ID = 26537

I had a few problem to put that radio on, one is to adjust/repair  the relay in decoder who torn on the lamp of FM-STEREO

Thanks Martin Boesch for alignment instructions

The Grundig work fine in my house everyday!!

Gentlemen,

please look 
here  /Mehr Pläne/ grundigdecoder6.pdf. for additional information and a wiring diagram in better quality.
Gary, do you know the reason for the misalignment of your decoder ? Please check the potentiometers (carefully !) and the pins of plug and socket-outlet for connection with the radio. They are usually oxidized.

Best regards
Rolf

Hello Rolf,
 
I appreciate your input. I have a copy of the schematic and other papers on the Grundig Stereo Decoder 6. I am also very thankful to Martin Bösch for translating the alignment procedure to English.
 
This decoder has been installed in a Fisher 101-R AM/FM mono tuner. (not by me) The tuner works good and the stereo light comes on, but audio sounds like mono (no channel separation). It worked good in past. Tubes are good. I think coils have been "adjusted"??
 
I have not been able to find a stereo generator on eBay. Difficult to find. Please look at this: http://www.helmut-singer.de/stock/1310.html - Is this same as Stereocoder SC 1?
 
Regards,
Gary

  8 Dear Gary,

as I told you in my email, the solution shown by you will be the best - I think this generator is refurbished and like new. But it is very expensive. My proposals: If you are not in a hurry, try at first a little printed board multiplexer from tugicom in combination with a signal generator or cd-player as source.  If you want to supply the radio from  "RF-direction", you could connect this generator e. g. with a FM transmitter from  ELV. 

Best regards
Rolf
