Can anyone advise me? I've come across an old turntable (Sony PS-LX220) with a drive belt detached. No manual with it. Any idea how to replace the belt? Do I open up the box? There's a pulley which spins when it's turned on, under the turntable itself, but as far as I can see it can't drive the turntable directly because it's not touching the side of it underneath, so it must need a belt.

If anyone has an illustration from a Sony manual on how to replace a belt, that might be the best help. Or any other suggestions?

Many thanks,
Patrick.
