Product quality flat belt made in EUROPE for DISC TURNER: PRO-JECT 1 (All variants) Not old stock, but only new and fresh from factory. The advantage of a belt drive is that absorbs vibrations that can occur only with a better content of natural rubber and other suitable materials that guarantee good wear resistance and the right traction, but without deforming. After experimenting for a long time, we got a good mix. The lengths of our belts are exactly adapted to the DISC TURNERS described, they are not extended with the "force" causing damage to the mechanics over time and the ability to absorb the vibrations of the belt. In fact, unlike many, we have a lot of measurements, and not only a few "standard". Im a true Vintage audio enthusiast, not just "I want to sell everything without knowing anything" and I always seek to offer good quality service. The my comments-Feedback prove it. I wish you a lot of fun with our long lasting belts.
