I hope you will understand (my) English. I dont know this model "Grundig Mandello radiomeubel", but from the late 50s to the 60s Grundig had a 5 pin DIN Jack on the back panel for plugging in a add on stereo decoder. On the back there was also an information about the compatible types (I have a radio where a decoder type IV (4) or V (5) is recommended). Type IV for example had only one ECC81(I found the circuit in the "Ratheiser"). Main difficulty in building one is making the coils for 19/38 kHz filter/bandpass (no data available). I solved the problem in a non puristic way - with a KEMO Stereo decoder kit with an ic (please don't beat me up!). But it sounds good. If there is interest, I can supply you with further information.
greetings
