VTF stands for Vertical Tracking Force. It is the amount of force that the stylus (needle) of a record player applies to the record’s groove. It is measured in grams. The VTF is important for two reasons:
- It ensures that the stylus makes good contact with the record’s groove, which is necessary for accurate sound reproduction.
- It prevents the stylus from skipping or jumping out of the groove.
To adjust the VTF, you will need a tracking force gauge. You can find these at most audio stores.
Here are the steps on how to adjust VTF:
- Make sure that your turntable is level.
- Place a clean, dry record on the turntable.
- Place the tracking force gauge on the record, so that the needle of the gauge is directly under the stylus.
- Adjust the tracking force knob on the turntable until the needle of the gauge is in the center of the scale.
- Remove the tracking force gauge and play a record. Listen for any distortion or skipping. If you hear any distortion or skipping, adjust the VTF until the sound is clear.
The ideal VTF will vary depending on the type of cartridge and record player. However, most moving magnet (MM) cartridges typically require a VTF in the range of 1.5 to 2.5 grams. Moving coil (MC) cartridges typically require a lower VTF, in the range of 0.5 to 1.5 grams.
If you are not comfortable adjusting the VTF yourself, you can take your turntable to a qualified technician.
Here are some tips for preventing VTF problems:
- Keep your records clean and free of dust.
- Use a tracking force gauge to check the VTF regularly.
- Adjust the VTF if necessary.
- Take your turntable to a qualified technician for regular maintenance.
By following these tips, you can help ensure that your VTF is correct and that your records sound their best.
