However you earlier posted a different Grundig schematic on another forum. It isn't easy to see but appears to follow the same arrangement as in the 80U. It the other case it is C53 that provides the DC block.
You mention a clearer version of the schematic - if you have it, perhaps we can all have a look?
I don't have any radios anymore.
No, definitely not....If you look at the schematic you refer to there's a dc circuit between the anode and cathode of the AM detector.....Anode>Last AM IFT sec>R37>R38>Function switch contacts 9k&9l>R28>Cathode.....
No direct link to the clearer schematic that was mentioned on the other forum, however, click on the link below and scroll down to HF35 to open the PDF (safe site so far as I know, been using it for ages):
