Vinyl record deck , cartridge / stylus question
 

Putting a new but old stock cartridge on a vinyl deck, I'm sure I remember
the problem from years ago but not the cure . Original cartridge & stylus
missing.
Right channel on loud sections has nasty , clipping like, distortion on one
channel.
Swapping cartridge leads the distortion swaps sides.
Maximum weight for this cartridge in the notes is 2 gm but distortion
disappears at 4 to 6 gms.
Is this a problem with radial,centripetal/centrifugal force compensator,
problem with the flexible suspension material on the end of stylus arm or
what ?

are you absolutely sure that the stylus shank is not bent (even
v.slightly?) that has caused exactly this symptom for me in the
past....

Is there any chance that the cartridge is a Shure where the
elasticizer holding the stylus shank has hardened up? Chuck

Forcing the arm outwards by pushing via a nylon cable tie removes the
distorsion and pushing inwards makes it worse so presumably needs more
anti-skating. I had to rebalance the tone-arm weight for presumably a
heavier cartridge than the unseen original, does that need more anti-skate
force , i thought it should go up with more stylus weight.

What's the arm? Are you measuring stylus force with a balance, or using
the numbers on the weight on the arm's counterweight? I'm sure you
zeroed out the arm before you adjusted the counterweight.

Proper procedure is to balance the arm--with anti-skate set to zero--to
the point where it is 'just' floating above the surface of the record,
set the weight indicator for zero at that point; then dial in the
correct stylus pressure. Usually I set for the high end of the
manufacturers recommendation. At that point, if a calibrated anti-skate
dial is present, I adjust that to the same setting as the stylus and listen.

It's important to do this in order. If you have to go grossly above the
recommended weight in order for it to sound 'good', something's
wrong...either with the cartridge, stylus or tonearm.

Be sure that the cartridge that you've fitted is set correctly for radial
displacement within the headshell. If the cartridge uses an eliptical sylus,
which most quality ones do, then if this is not correctly aligned with the
groove, asymmetric distortion can occur. Stylus overhang should also be
correct, but this usually requires a gauge specific to the deck / tone arm
to set.

Sounds like anti-skating force is off. Has to match weight.

This assumes that the turntable is level to start with, of course. Check on
turntable itself, not base.

Problem seems to be I only had a mono LP from 1963 and using an eliptical
stylus.
Borrowed a copy of Neil Young - Harvest and problem evaporated
