In the modern era, the service manual has become a foundational text for the "restomod" community. While companies like Schopper Swiss Hanze HiFi
Reassemble the bottom cap with a new gasket to prevent leaks. Fill the housing with factory-weight oil (typically a straight SAE 20 or specialized Thorens bearing oil). Slowly lower the spindle back into the housing, allowing air to escape naturally. 4. Addressing Common Issues (Troubleshooting) Probable Cause Service Manual Solution Excessive Rumble / Noise

– grey paint, a revised nameplate, an aluminium (non‑magnetic) platter, a more powerful motor, and a revised motor suspension that uses double rubber grommets instead of single ones. The MK II is also considered quieter when used with modern MC cartridges, though the rumble spec for both generations is around –45 dB (NAB standard). Neon glow lamp (requires specific resistor drop for
The E50 motor is robust, but the oil‑soaked felts can dry out. A full motor rebuild involves:
The manual includes a schematic diagram (the "service manual electrical scheme") covering the neon strobe light circuit and the voltage selector plug. This is vital for replacing old capacitors or fixing a non-functional strobe disk.
: Check that the rubber tire hasn't developed "flat spots," which can cause vibration. If it has, a replacement may be necessary to restore low-noise operation.
Some owners choose to replace the original rubber grommets with after‑market spring suspensions that lower noise transmission. The service manual gives the original motor mounting geometry, so you can verify that any after‑market upgrade keeps the motor pulley aligned with the stepped pulley. Slowly lower the spindle back into the housing,

To accommodate modern Moving Coil (MC) cartridges.
The manual calls for a specific viscosity oil (ISO 68 or 220 depending on revision). Many modern restorers use synthetic motor oil or Thorens original oil (available from Schopper). The manual shows exactly how much: fill until the oil level is 2mm below the top of the bearing housing. Too much and it leaks; too little and the spindle seizes after 30 minutes of play.
