I found the solution:
the internal speaker is "a kind of" defect.
By pluging in an external speaker, no distortions are there.
Thank you all for helping me.
I have another problem with that trcv but I will open a new
thread if I find nothing in the archive...

@Spence: well great Idea!
I will record a video and upload it to youtube. Then I share
the link here...
It takes a couple of days since I am in
vacation now.
@Andy, I speak about low frequencies (ca.
300 ... 800 Hz) and not low volume.
The effect can be shown by putting a sound generator at the
input of the TDA and wobble the frequency then...
I'll be back after my holidays...

M0STO via groups.io:
Can I please inject a suggestion.....?
Make a short video and post it on YouTube as private for
those with a link so we can all see the issue.
? Failing that I will create a guest account on my FTP
server and upload it there!
De Spence M0STO?
Sent while portable! please
excuse typos.
When you say "at low audio frequencies", do you mean
low frequencies, or low AF Gain on front panel?
I think there may be a translation problem.

Andy
