I own a Beogram 6500 I purchased new. Now, when I play an LP it starts off fine but as the arm reaches about halfway across the album, a rythmical mechanical grinding sound, the frequency of which co-incides with each reevolution, begins to appear as though one part of the turntable is fouling something. The sound increases as the arm continues to move towards the centre of the LP and I detect some wow in the sound quaility.
There are no visible signs of wear on the edges or the underneath of the turnable suggesting that it is in fact rubbing on something, and no obvious visible cause.
Have any members experienced similar problems or can offer suggestions as to the cause/solution?
I have really looked after the item and am most anxious to get this problem resolved quickly.
It's most likely to be the platter scraping on parts of the main chassis and the weight of the carriage, tonearm etc.makes the platter sit lower and lower, even if very little, at the left side as the carriage travels left.Adjust the platter (subchassis) height. It's mentioned in the service manual.

I down-loaded the service manual, removed the platter and black plastic grill at the rear of the Beogram 6500, adjusted the subchassis height and VOILA!Job done, it's now operates as quiet as a mouse. Once again, thank you so much for your advice.
