I am trying to align the radio without the instructions.
Which is OK. I'd still like to have the alignment instruction, considering the bands and the oscillator have both trimmer caps and trimmer coils.

But I have started with IF, which is 473kHz, and while I successfully passed it via antenna input (this one has no grid caps to disconnect), the trimming is a whole different matter.
The IF is adjusted by the screw core, and while the ones at the bottom of the IF transformer are easily accessible, and I was able to mold a tip holder of a ball pen to be my socket driver, the ones accessible from the top are about 1/2" inside the bobbin, and the diameter of the inside of the bobbin is about 1mm wider than the core's hex width (4mm side-to-side, 4.2mm corner-to-corner).

   
   

I am trying to figure how to access it. It needs to be hard plastic nut driver with very thin walls. I am sure there was such a tool available to Telefunken techs, but, well, those wonderful days are long gone.

Time to join Radiomuseum. I am sure there are folks there with this specific experience.
