Right Channel noise with contact line stylus

Post by AleA6404 » 18 Jun 2019 02:05

I am experiencing a noise issue with my higher end cartridges that have "contact/fine line" stylus's. I hear a noise from only the right channel on the first few tracks of some of my records. I have changed tonearms, turntables, preamps, cables, etc. but, none help. My other cartridges with spherical stylus do not exhibit this problem.

One cartridge vendor told me that this is a common issue with these types of stylus's. If so, then, many others must be experiencing the same issue.

So, I want to see if anyone on this forum has had similar experience and if you have been able to identify the cause and the remedy.

Alex, sorry I can only wonder whether Dual's recommendation of higher anti-skate settings for shaped styli might suggest something else to try? No personal experience, just something I've wondered about. Good luck -- must be frustrating.

Adjust anti-skate.

Check the records for flaws, pressing defects, etc.

Note that if the record is not perfectly pressed on center you can sometimes hear noise in one channel as the arm moves from side to side and the stylus bounces around in the groove.

check azimuth too. imbalance of antiskate or azimuth may result in one channel having more/less distortion than the other. i have this issue on some of the records as well, could be pressing too.

I have tried those and have not helped much. A large enough percentage of my records exhibit these issues that I am really interested in understanding it. Besides, it is not distortion. It is noise. I am interested to see if anyone else no this forum is experiencing the same thing.

I don't see where the type of stylus, has any bearing on hum.

It is not hum. It is scratching / scraping sounding noise.

Maybe fool around with a different alignment other than what you're using right now? If it's always the first few tracks, sounds like that could be a solution.

Did you raise the anti-skating force?

Cheers,

Be careful with alignment.
A misaligned fine tip can become a chisel.

Conical tips will not exhibit that behavior since they are round.

I posed the question about noise from the right channel to a cartridge expert. He did some research, including talking to people who cut and press LPs. His finding is that the source of the noise is the separation of LP from the stamper. If release agent is not used, the outer grooves can get burrs in their upper part. Styli with smaller contact area do not touch this part of the groove, but, line contacts do. This is the best explanation I have heard so far.
