Many thanks Mr.Bauer,
the attached picture shows what I have on my radio. As I told, the red wire is not connected, the black one yes.

Hello Mr. Russo.
Something is missing.
The variable capacitor is mounted wrong (crooked).
Something missing here a Tab or a nut?
See images.
There's a picture of identical Grundig 6001.

Good Morning Mr. Bauer,
thank you for the information.
I'll remove the capacitor and I'll try to rebuild it.
Probably the black wire is connected to the capacitor's "moving" side, so I should connect the red wire to the fixed side of the capacitor.
By the way, I have just another question about the band spread push button:
has this button 2 stable positions, up and down?
I mean, stay the button down also without pushing on it?
This question comes because in my radio the steel ring under the button was lost (please see the attached picture).
I put a similar ring and the button is correctly pushed-up by the ring force but the mechanism doesn't act as 2 stable positions.
I hope I was clear.

Missing a small spring
As I can remember from mine, your radio had missing a small spring, something like a small paper clip, with V form. This "spring" act as a elastic union between both switches, the upper and lower.
The plain screw is used to adjust the position.

Many thanks Mr. Bayon,
during the weekend I rebuilded the varicap as showed in the attached pictures.
I think it should be right.

I think it's ok now. My radio have this contact broken and I have done the same repair. Put some paint or laque on screw/nut to prevent a unscrew.

Good idea and probably could be useful to glue or tighten the two plastic parts, top and bottom, in order to avoid variation in capacitance due to the distance alteration (see first picture from Herr Bauer).
Thanks

Don't use loctite or glue !!
Loctite and other types of glue use solvents that could evaporate and solve the small dielectric plastic !!. So beware with this. Put only a very small amount of paint (better if it's water based )
I've ruined some variable capacitors because this.

Small var cap and spread band button

Good Morning,
perfect I'll try to use paint.
By the way, Mr. Bayon, do you remember if the spread band push button is double position (please read my message number 5).
Many Thanks!

Band spread switch
Of course, the band spread is a two position switch, with locking. On first push down, swith must lock and stay in lower position. When you push it again, the switch release and stay in upper position. This lock and release it's done, as I can remember, with the upper part of the switch (the brown one in your photo).

Band spread switch

In fact. Probably something is broken/missed.
I'll try to remove the mechanism and inspect it.
Thanks
