The speakers to me are special being Goodmans Mezzo 2, said to be the best of the best when they came onto the audio scene around thirty years back?
The turntable is a Yamaha P-320 and looking at its inside, plus the cast alloy turntable disc, its clear to see Yamaha made that well too.
When the alloy table was removed, I found a probable cause of noise right away, the rubber belt drive pin was quite loose, plus it had a central and uneven build up of rubber that had come off the two belts used in its lifetime, this I managed to remove with my finger nail. On closer inspection I found the rubber bushes around the mount screws had shrunk.
With the bottom cover screws removed, this includes the four spring mounted rubber feet, I could access the works and see if any obvious faults existed?
The drive motor is the small round item on the right with yellow,white,black and red wires coming from it.
Remove all 10 screws, lift the metal cover from the side closest to you in the picture, hinge it back and then find the small earth cable in the back left hand corner, do not break the cable or its soldered joints.
The Yamaha drive motor, I brushed the inside of the player to move dust, then vacumed it clean.
To refit the alloy table, mount the drive belt on it, then fit the table on the center pin, you can then access the belt and move it over to the drive pin, a toothpick will suit this job.
The model number.
Ready to play again, make sure you refit the rubber mat the right way up.
Check the three crossed tuning forks, proof that its a real Yamaha!

A test play had me listening to some clean and pure audio sound, the fix worked but I still get feedback from the left speaker when the stylus is down and I tap the plastic dust cover lightly, why?
I now suspect the stylus fitting, as fitting another stylus reduced the side noise.
