The Beogram probably needs a new drive belt.

What's the problem? Distorted sound, wow&flutter or something else?

I've had problems with distorded sound on quite a few 180g vinyls on my bg7000. The same records sound good on my Pro-Ject turntable (that I have hidden in a cupboard, haha), so the records are ok. It's just like the bg7000/mmc1 can't track these records correctly.

Ah ok, speed issues. Then follow Graham's advice. :)

These tangential turntables are 17+ years old and they ALL need at least a new drive belt and possibly a new servo belt.

It is by far the cheapest way of improving the sound quality of your turntable.

Every turntable I sell gets a new drive belt and then tested with a 180g vinyl copy of one of my test records.

They all sound fantastic.

Hi

I have a BG3500 and never had problems listening to 180g vinyl records. Also my former turntables (BG3000 and BG6500) which have almost the same mechanics never had problems with 180g vinyl. 

They really sound fantastic, so it is worth the work or money to repair.

Thanks for all your advices, I have ordered a new drive belt from my dealer.

 

Just need to know what is the servo belt... And if it needs a new one.

As far as I am aware the belts are no longer available from B&O. You would be better of ordering from Beoworld member Dillen .

The servo belt drives the gears that make the arm move across the record. They need replacing less often than the platter drive belt, in my experience.

Raise the weight ever so slightly. 180gm vinyl was very rare when these decks were new.
