Grinding sound on record

[Ilovemydog51]

Hi all,
On my turntable my records keep making a grinding noise during quiet sections (such as lead in groove). I will provide videos at end. The noise isn’t bothering me as the music sounds perfect but I was just wondering it was damaging my records. My turntable is a dd-2250 omintronic with a ortifon reloop Concorde stylus. The turntable is fairly old but the stylus is brand new. Btw I have two of these tt and two of the stylus and they both have the same problem. It is hardly audible when the volume is at zero and I have to put my ear right against it. It also increases when I increase the volume. I took the platter off to see if there was anything obstructive and there wasn’t. However when I turned on the tt with the platter off there was a loud sound that was similar to the grinding noise but it stopped when I put the platter back on.
These are the links.
as I’ve said before the noise doesn’t bother me I just don’t want to be damaging my records.
Thanks

sorry but this forum won’t allow me to post links to the videos

Sounds like it could be a Bearing or motor problem which is getting transmitted through to the record, remove the platter and make sure there is no play in the bearing and there is no debris between the bearings and motor windings, if all clear than you will need to take it to a service centre to have it fixed.
Don't leave or ignore it, as it could get worse and cause even more damage which will cost you even more to get repaired.

Presumably it's the same with all your records?
I only ask because pre-music (and during music) unwanted noise(s) can be an issue with rogue vinyl.....and it can manifest as a slight grinding or scraping sound.

Yes it’s the same with all records I play. I also have an lp60x and the grinding noise is not audible there. I’ve seen other people elsewhere say that dj turntables and equipment can result in these noises and don’t do any actual damage but I’m not sure how reliable that is.

Also I’ve seen others say that if the noise increases with volume and is barely audible when volume is at 0, then the problem is electronical and is not damaging records.

Makes sense but ie cannot confirm that is true.

Yes, that's because, as you say, a mechanical noise is finding it's way to the stylus - which will be heard through speakers (and therefore will go up and down with the volume control).

But, importantly, it's the source of the noise that needs to be rectified.
