Pro-Ject Debut Carbon Noise issue driving me nuts!


I have a problem with my Turntable humming ONLY when the stylus is on the album. As the volume goes up, the hum is more noticeable. Once I lift the stylus, it’s quiet as a church mouse.

ive tried new cables, verifying the grounding, setting the table ona block ...nothing. I don’t think it’s a grounding issue so I’m at a loss. Does anyone have any ideas?

thanks!

@bigjohn9095....

Just my opinion....

If the cartridge is ONLY picking up noise when the stylus is in contact with the table, then logic seems to be that the noise is coming from table vibration.  Something is in contact with the plinth or bearing that is humming.  

Look around for the culprit.  Maybe the table itself needs more isolation.  Maybe something is resting against the table that is causing the noise.    Try placing it on some paperback books to see of the noise is originating from your shelf.  If you have any Vibrapod pucks, place them under the feet of the table.

If the noise is unchanged, them check to see of the motor is adequately isolated from the plinth. 

I agree that the problem might be from the cartridge itself, but lets try to isolate the table before spending more money on a different cartridge.

Those might be a couple of starting points you could easily try.  

Just my opinion.  Take it for what it's worth.
