I have used the spectogram view to locate the missing cracks and it quite worked well. ...
Though there are still extremely tiny cracks I can percieve but not locate ...
If you can hear them they will be visible on the spectrogram,
but you may have to adjust
the spectrogram settings to see them.

What are the "spectogram tools" ...

I have been trying the spectorgram tools and watched the video but that seems a bit complicated for me.
I tried the equalizer for some noises too and it worked for a noisy segment. Now I have some static/interferences I can't figure out how to remove.
Here is the sample with a screenshot of the graphic with 2 different spectogram view settings.

So, if anybody can help with that, it's welcome.

Reduce the
spectrogram FFT window-size to 128 to see clicks.
The clicks will be easier to see if you apply this sort of equalization first to "sample.flac (146.6 KiB)" ...

Thank you. I did what you suggested but it didn't work.
Here is the graphic at 128. The equalization you suggested didn't remove the clics/cracks/parasites :-/
The repair tool is not working either on these. It actually makes it even worse.

I didn't claim it would: removing that trebley noise makes them more visible on the spectrogram.
Something has gone wrong when you captured that vinyl to produce the loud fizzy noise at 9-10kHz.
Try the RIAA equalization curve ...

If the recording distorts due to excessive volume, you could try setting phone/line on the turntable to phono, but the recording may then sound "tinny" and lacking in bass because RIAA equalization has not been applied. To correct lack of RIAA equalization after recording, open Effect > Filter Curve EQ or Effect > Graphic EQ and apply the "RIAA" curve to the recording.

Hello. Thank you but actually I did not rip the vinyl myself. Someone has bought it for me and ripped it (I don't have a vinyl player/recorder myself). However, I checked some other versions of this track online and they all have these small parasites at the same place in the audio. It must be on the original recording. But that doesn't mean it can't be removed or that it should stay there. But it seems that it will stay there as I can't find a way to get rid of them, at least without damaging the song/sound.
