Run in the belt for 50 hours and then repeat you method of measurement
The belt drive system adds another layer of "settling" time. The belt itself needs to stretch and adjust to the platter and sub-platter as the turntable starts.
Yes, a rubber band needs to settle. Bring on the naysayers! ;)
Yes, Rega turntables, particularly the Planar series, can take a bit of time to settle into their speed after the belt is engaged. This is normal and often attributed to the design of the low-torque motor and the nature of the belt drive system.
No, it's not possible to create a rubber band with perfectly exact elasticity. While rubber bands exhibit elastic properties, they don't behave perfectly according to Hooke's Law, and their elasticity deteriorates over time due to factors like UV light, temperature, and stress.
Hooke's Law states that the force required to stretch or compress a spring (or a material exhibiting elastic behavior) is proportional to the displacement. However, rubber bands don't perfectly adhere to this law. While they initially exhibit a linear relationship between force and extension, this linearity breaks down as the rubber band is stretched further.
Rega belts are tested:
Yes, Rega drive belts, including the Reference EBLT, are extensively tested to ensure accuracy and consistency. The Reference EBLT is molded on custom tooling, cryogenically frozen, and barreled to remove flash, resulting in a cross-sectional roundness of 0.075%. This process guarantees the highest achievable level of accuracy.
