is it ok to attach a Ferrite to my earth cable on my Tonearm.
You wont do any damage if you try it. It might help but I suspect you need to look into how good the earth is. The buzz could well be a bad contact or misplaced earth or indeed an earth loop.
Welcome to the forum.
Hi Robinho. I’ve tried that with the Ferrete & it’s made a difference but I still have a very faint buzz from the Cartridge to head shell wires but I think that could be because my one speaker is only 12” away from the tonearm ? So in this position I can’t move any of my units around so I’m going to make sure that the earth cable can be moved on the connector & try again.. but it’s not a big issue really but just one worth mentioning on here for others to try if they fell it would help.
If you have hum/buzz coming from a tonearm, with the cable properly grounded to a phono-stage, then you probably have a fault with the tonearm cable itself, either internally or in the connectors (head shell pins or termination at phono-stage).
I doubt a ferrite on the cable is going to solve the problem. I’ve been down that road. My tonearm had this problem and it finally lost a channel altogether. Apparently the internal wiring was faulty. The tonearm was replaced under warranty, and that resolved all the noise issues.
I did try to see if it worked better with the ferrite but found that there was no difference ?? but when i put my finger near to the cartridge wires I get more sound. I’ve also fitted a new Linn Adikt cartridge & it is now weighted at 1.67grams where has before I had it at 1.16grams ? so now looking at that as my next step forward because the wiring seems to be ok as it is on my Linn Basik LVX tonearm after cleaning the headshell conections with Ispropanol cloth.
