If the record is skipping then it is technically jumping the groove... The cartridge could look fine and still be suffering from suspension problems. The rubber inside can become hardened and this will prevent proper cantilever compliance which could theoretically cause the record to skip. 

What I don't understand is how it would play old records correctly but not new ones.... 

Can you tell us exactly what you do to set the tracking force? I'm convinced if the stylus and cartridge are in good shape this can be the only cause...

Also out of interest, what's the name of the records you're having trouble with?

Just wanted to chime in that I have never had this problem with an MMC4 and a radial B&O, in my case multiple RX2's. In fact the one the would-be burglar threw on the floor was finally set right over the weekend and played the 180 gram reissue of LZ IV just fine.

And to answer a question from before: naff is not good. In plain terms Lee's opinion is the B&O is clearly superior to the Pro-ject.

Jacques had an issue earlier in the year with an MMC and distortion. I don't think he ever figured out the issue he had. Sometimes with complicated systems it's an interaction of multiple minor issues that cannot be isolated.

I had the same problem with my 4002 and MMC20CL. After a retyping by Axel, no more problem ;).

For sure, these records could detect early suspension problems (in my view).

Yes please post a video so we can see what is actually happening. I suspect that you've got a damaged stylus to be honest. The Beogram 5000 should have no problem whatsoever playing 180g vinyl... It's actually a better built deck than my 5005 and that plays 180g and 200g vinyl without issue. 

 

Hello fellahs,

So sorry it took so long to respond.  Had to find time to take pics and a video. 

Please take a look at the pics below, and the link to the video.  If anything looks to be out of sorts, please let me know:

Have you set the anti skating? I'm pretty sure underneath the Beogram there is an adjustment for skating.

Check service manual and it explains how to set.

Has the tone arm been calibrated recently?  The 1.4g you're dialing in could easily net out to be closer to 1.0g - too light (tho some records might play ok at a light tracking force).
