- Improves motor decoupling
- Reduces unwanted resonances
- Improves overall performance
The S/E Upgrade Kit is an affordable motor upgrade package for selected turntables, designed for historical Pro-Ject owners looking to get more out of their existing system. This simple but intuitive kit, developed specially by Henley Audio, improves motor isolation to the modern standard employed by the latest Pro-Ject turntables.
The package includes:
- 2 Rubber Gromits and Screws
- Rounded Drive Belt
- Alternative Pulley
The rubber gromits are designed to sit underneath the motor, and are secured in place by the supplied screws (using the existing holes in the plinth for the motor transit screws). By tuning the pressure on the gromits with the screws, the result is a dramatic reduction in unwanted vibrations from the motor, causing less resonance in the overall sound performance.
The new pulley is fitted to the motor by removing the existing pully (there may be a small screw holding the existing pulley in place - this needs to be removed), and fixing the new unit in the same position. The rounded belt is placed into position in the same way as the original drive belt. These simple steps help reduce the transfer of any remaining resonances to the record surface.
"Measured against the default sound of the turntable and that of my fix, the new system produces a sound that is practically unmeasurable against the sound of the amp and the room."
