No old stocks, but new and factory fresh! Quality flat strap manufactured in fresh Europe for turntables - LINN SONDEK LP-12 KLIMAX the advantage of a belt drive is to absorb the vibrations of the chassis and those of the engine that is only possible with the best straps with a high content of natural rubber and other matching materials that ensure good wear resistance and the right traction but without deformation. After many experiments and tests, we have reached this winning mix. The lengths of our straps are always exactly tailored for the model of turntables described, they are not adapted and stretched to allow them to enter by "force" damaging the mechanics over time and removing the strap, both the duration and the ability to absorb vibrations well. Because unlike many we have many sizes, not a few "standard". You do not have to worry about the mounting direction because smooth on both sides. I am a true vintage audio enthusiast, not just a : "I want to sell everything without understanding anything" and always try to offer good quality with criteria. My feedback proves that. Wish you a good fun with our long lasting straps!
