VPI JMW9 Sig. Arm Tube Ringing. Any remedies?


The mere stylus/record contact during silent passages excites a ringing during playback and is especially audible playing loud cut records with heavy kick drum. It appears to originate from the tube while holding it at the fulcrum and tapping the arm tube with a fingernail. Has anyone found a remedy to effectively drain/mute this resonance without adding much mass to the arm? The effects of this are very annoying. Has anyone using a Benz Micro Ebony 3H or equivelent mass cart replaced the arm with something else and what was your results?

Before making any mods to the arm (no offence Lwerener), I'd make sure the arm is functioning as intended. I have never heard a ringing when playing either the 9 Sig, or the 10.5i that I'm currently using. You may also try damping the arm slightly...only a few drops of the damping fluid or you'll close in the sound too much. I find that it sometimes makes a positive difference. Are you sure that your arm is seated properly on the bearing pin?
This is from the VPI website, a comparison of the jmw9 arms:

INTERNAL DAMPING
1.7 POUND DENSITY FOAM
2.5 POUND DENSITY FOAM

Something else must be wrong, I would contact them.
Lwerner, That would be a last resort but I won't discount it. Stringreen I added a little bit of oil a while ago to the pivot but I don't want to add any more. Storyboy, Thanks for the info. I will call VPI and get some input from them.
