↺ Anti-Skate Guide
g
- 💡What is anti-skate? A bias force that counteracts the inward pull (skating force) generated as the stylus tracks the spiral groove. Without it, the stylus presses harder on the inner groove wall, causing channel imbalance and distortion.
- 🎤Testing anti-skate Play a blank/silent runout groove — the stylus should sit centered. On a normal track, right-channel distortion before left suggests too little anti-skate; left distortion first suggests too much.
- ⚠Spherical vs line-contact styli Line-contact, Shibata, and microlinear styli generate different contact forces — you may need slightly less anti-skate than your VTF reading suggests.
📏 Cartridge Alignment Geometries
Select a geometry to learn when and why to use it.
Baerwald (IEC)
Minimises distortion over the entire playing surface by spreading null points across the record. The most widely used geometry.
Most PopularLöfgren A
Mathematically identical to Baerwald. Minimises RMS distortion across the full record surface. Null points at 66mm and 120.9mm.
Low RMS DistortionLöfgren B
Optimises peak distortion rather than average distortion. Null points further apart; better for audiophile listening at inner grooves.
Low Peak DistortionStevenson
Places one null point at the innermost groove. Used by many Japanese cartridge manufacturers. Prioritises the end-of-side where distortion normally peaks.
Inner Groove Focus🔃 VTA / SRA & Azimuth
- 📏Vertical Tracking Angle (VTA) The angle of the stylus cantilever relative to the record surface. Ideal SRA (Stylus Rake Angle) is 92°. Start with the tonearm parallel to the record surface.
- ⬆️Tonearm too high (rear) Cantilever tips forward — treble sounds thin and bright, bass can become woolly.
- ⬇️Tonearm too low (rear) Cantilever tips back — can add warmth but muddy midrange and compressed soundstage.
- 📅Record thickness matters A 180g pressing is thicker than a standard pressing. If you frequently switch between them, consider adjusting VTA per side.
- ✅How to set Set tonearm parallel first. Then raise or lower rear by no more than 1–2mm at a time, listening for tonal balance changes.
- 🔃What is azimuth? The rotational alignment of the cartridge in the headshell — whether the stylus is perfectly vertical (90°) to the record surface when viewed from the front.
- 🎤Why it matters Incorrect azimuth causes channel crosstalk and phase errors. The left and right groove walls are cut at 45° — any tilt reads both channels simultaneously, blurring the stereo image.
- 📏How to set Use a mirror or smartphone camera facing you to check the stylus is vertical. Advanced: use a test record with crosstalk signals and a multimeter or software like REW (Room EQ Wizard).
- ⚙️Adjustment Most cartridges align to the headshell slots. Some tonearms (SME, Graham, Triplanar) have dedicated azimuth adjustment rings. Small rotations matter — a 1° error is audible.

🔧 Maintenance Schedule
| Frequency | Task | Why |
|---|---|---|
| Every play | Clean record with carbon fibre brush | Removes loose dust before the stylus does |
| Every play | Dry-brush stylus (front to back) | Prevents groove debris buildup on the stylus tip |
| Every 20–30 plays | Wet-clean records (enzyme cleaner or RCM) | Deep cleaning removes embedded grime and mould release compound |
| Monthly | Wet-clean stylus with stylus fluid | Removes bonded grime that dry brushing misses |
| Every 3–6 months | Clean and lubricate tonearm bearings (if serviceable) | Friction-free bearing movement essential for accurate tracking |
| Annually | Re-check belt condition (belt-drive tables) | Belts stretch and degrade, affecting speed accuracy |
| Every 2–3 years | Re-lube platter bearing | Prevents metal-to-metal contact and noise |
| At stylus life | Replace or inspect stylus under microscope | Worn styli damage records and degrade sound significantly |
📚 Quick Setup Checklist
- 1️⃣Level the turntable Use a spirit level. An unlevel table causes speed inconsistencies and skating force imbalance.
- 2️⃣Set tracking force Balance tonearm to zero float, then dial in VTF using counterweight.
- 3️⃣Align cartridge overhang Use the protractor that matches your chosen geometry (Baerwald recommended for most).
- 4️⃣Set anti-skate Start equal to your VTF, refine by listening.
- 5️⃣Check VTA/SRA Tonearm parallel to record as a starting point, then fine-tune.
- 6️⃣Verify azimuth Stylus should be visually vertical from the front.
- 7️⃣Set phono stage gain and loading MM: 47kΩ loading, 40–50dB gain. MC: check manufacturer spec.
