Is my stylus miss-tracking?


I’m experiencing a slightly fuzzy or static sound in the right channel at high volumes on some records when the passage is complex and loud. It seems to happen when high frequencies are playing. I swapped the speakers and it stayed on the right side so it’s not a blown tweeter. Could this be an antisate problem? I’d like to say I’ve played with adjusting the antiskate but to be honest I’m afraid of breaking my tonearm again. I have the Clearaudio Magnify tonearm and the antiskate adjustment is a dial that you turn to tighten/loosen a tension cable. Not even sure which direction to turn it to make adjustments anyway. The manual is a bit unclear to me. I broke the tension cable the last time I messed with it. Any ideas on troubleshooting this is appreciated. Thank you!

There is no physical change to stylus/groove/speed interaction relative to volume.

I am going to presume: the noise is there at low volume, only readily apparent at loud volumes.

Assuming the cartridge/stylus is undamaged, not worn out:

My Guess: Anti-skate too low or too high may be present, but is not the problem. Many play with zero anti-skate. I hear l to r imbalance when it is off, but not the described noise.

I suspect your AZIMUTH is incorrect, the stylus ’crooked in the groove’ a bit. That can/will make those kind of noises, and again I suspect the noise is there at low volume, only readily apparent at loud volumes.

How does your TT arm allow Azimuth adjustment? Do you have a removable headshell?

IF so, some headshells provide for azimuth adjustment, here’s one, metal ones exist also, ebay:

 

My method to set azimuth is use a mirror the thickness of an LP, under the cartridge/stylus when adjusting. Amazon:

 

These acrylic blocks with grid lines are helpful

but the mirror: view from the front, any slight deviation from straight will be reflected ’opposite’ in the mirror, thus easy to detect.

Sometimes the cantilever/stylus tip is not perfectly aligned with the cartridge body or headshell, so concentrate on the stylus/cantilever.

IF your cantilever is ’bent’ off-center, ’too much’ which can happen, then errant noises can occur, revealed at high volumes.

By the way, an easy way to adjust anti-skate is visually, via a blank grooveless LP.

  1. CARTRIDGES

$15. ALIGNMENT DISC: one side: Lines for Overhang and Two NULL Points

ANTI-SKATE: other blank side: spin platter manually, adjust anti-skate control while watching

1st: no anti-skate, set tracking force.

next set anti-skate. forget the dials/scales, set it visually:

blank side up, spin manually: no anti-skate, it pulls in to the center. add a bit of anti-skate, pulls in less. more anti-skate, less.

eventually it pulls out, that’s too much. Find an amount that keeps the arm steady at two points, like the inner and outer null point locations (no need to be perfect) If seems rignt but not always steady, go for slight inward pull rather than outward pull.

btw, I am assuming your TT is level,

check it as close to the arm base as possible. Then check on the platter, rotate, good in all directions? IOW, verify the arm is correctly mounted, plinth/platter all properly parralel/vertical to each other

breaking a wire trying to adjust anti-skate is very strange, had to be unsettling.

IF you cannot get your (any) arm to ’float’ using the blank disc/visual anti-skate method, there may be something errant going on with the arm’s pivot (or alignment to the plinth/platter as noted above)

Once the tiny silk covered litz wires out of the rear of my tonearm were just touching the edge of the rear vta/micrometer plate as the arm rotated, resisting free movement just a speck. I simply moved the wires a bit away from the plate (with a toothpick), problem gone.

Another time, bearings were too tight. Took a college try, arm out of base, loosened them, cleaned with alcohol/compressed air, snugged them up just so, problem solved. 1st and only time I messed with bearings, got lucky.

A final thought:

Perhaps the tracking force is too little, and the stylus is jumping about in the groove only at high frequencies with the incredible amount of rapid movement high frequencies have.

IF you set anti-skate, or have anti-skate active in any amount, other than zero, and then set the tracking force, that is incorrect, and the tracking force will not be accurate when playing.

Always reduce anti-skate to zero. Then set downward tracking force, then ’add’ anti-skate’ outward pull visually as described above.

If the cartridge has a range of tracking force, try the highest amount of that range, any difference?
