Hi, it may be a long shot:

See the second post.

Seems loss of all AM bands is a common fault caused by a dodgy trim cap - C138.

Thanks Phil, I read right past this clue and missed it.
However, it was not C138, but another one nearby, C130. They are not on
the RF board but on the processor board underneath (in a can...).

It's easily identified by the fact that it is actually accessible
through a hole in the RF-PCB above and in the can below.
There is a handy hint for any one chasing this fault!

If one doesn't want to go so far and actually replace this trim C there
would be *no need* to take out the RF board, unsolder and bend out the 4
lugs of the shield cover of the processor boards and so on, a real PIA.
Just reaching through the hole with a trim tool and lightly tapping on
the variable cap is a quick fix. Good enough for me for now, I'll see
how it goes. But if one needs to replace the lithium memory battery
there is no way around this awkward job though.
