Don't forget to oil the vertical pivot points, and don't forget to lubricate the moving parts of the drive system. Don't oil the velocity trip clutch, though, if this unit has one. If this unit has a rachet trip, then you can oil everything. A rachet trip makes a clicking noise as the tone arm is moved toward the center of the record, and the system doesn't trip unless the tone arm is moved back towards the outside of the record. A velocity trip system trips as soon as the tone arm starts moving quickly towards the center of the record.
