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!

My dealer has one of these on permanent display/use in his shop. I once remember firmly gripping the arm’s finger lift, with the platter spinning, and actually feeling a very faint vibration that would probably cause hum noise once the stylus gets sandwiched between the vibrating headshell on one side, and firm platter/record on the order side.

Other users of this table have complained about poor isolation between motor and plinth being a culprit for this. I believe you should be able to tweak things to mitigate the vibration bleed. Later production models may have addressed this? Either way, I’m not a fan of these tables.
