As the subject suggested this is a stupid question from a newbie. I
wonder what is the sticky glue-like stuff in dark color that is near
the counterweight whole where the armtube goes through.

Probably a form of vicious silicon used to damp the tone arms motion
going up and down.

Vicious is right. Put on the wrong album, and it'll have its teeth in
your throat before you know it.
