Looks like you are missing the mat and mat ring, so unless you have those then you need to source replacements. Otherwise:
- Give it a clean
- Check it spins at the right speed and sounds fairly quiet in operation
- Find your least preferred LP and see if sound comes out
- Replace the cartridge/stylus before you play anything else
I would be concerned that the state of the TT is too bad to be worthwhile, but the images may lie.
If you are serious at getting into vinyl then, I'd look at a new Rega P1 or one of the budget Pro-Ject TTs.
You can get the Roksan Attessa on sale from Richer Sounds for £399 which is a bit of a bargain. Sign up to VIP for that price.
