I, too, find Grundig circuit diagrams a bit difficult to follow, despite having worked for 23 years for a Blaupunkt Car radio dealer. Got used to their diagrams I guess! As to the DC conditions of the Emden, they're similar to those on the diagram, so I'm still puzzled, not least by the fact that two of the eight connections on the AM coil pack read o/c, but I'm not sure whether there are meant to be 3 or 4 coils present. There are only 3 cores in the 'variometer' as I've sometimes seen it described. Gues I'll have to 'bite the bullet', remove and open the AM coil pack to check. Pity there isn't a PCB layout on RM.
