I have a record player, and I want to eliminate the irritating 60 hz tone that it produces, irregardless of if there is a record playing or not. I have tried grounding it, and if I unplug a single RCA cable from it the humm gets worse. Grounding the reciever did not make a difference. How do I get rid of this? I have read I may need a new needle/cartridge. Is this true? Thanks!

This is a ground loop caused by a bad ground or just plain bad cables. Make sure the record player is grounded properly to the receiver and make sure your patch cords aren't defective. I have never seen a bad cartridge cause a hum.

Since you have a secure ground from your
receiver's chassis to your turntable's, your
RCA cables sound like they may be the
culprit and need to be upgraded to some
higher quality cables. It appears that the
cables are not grounding the turntable
properly (perhaps a poor design or some
of the wiring within the interconnect is broken).
If you try that and still have the same problem,
I would recommend having an experienced
technician look at it.

That is very annoying. It's happened to me more than once. Mrknosita is very likely right about what the problem could be. That is the most common culprit of hum. However, in one incident with me, my cartridge headshell connection was at fault. So you may want to look into that also if the other suggested fixes don't clear up the problem. Good luck.

How previous is that this checklist participant and how fancy? The older sort of motor relies upon on the means frequency for it somewhat is velocity. utilising 50 Hz means skill it is going to run sluggish. I actual have seen what are in certainty adapters on the motor shaft of a few checklist gamers. They boost the diameter of the motor shaft that turns the platter the checklist sits on. This will boost the cost. extra moderen gadgets run on DC and have fantastic adjustments on them. It would not sound like this could be a form of.

Although I'm not familiar with record players, I can tell you that hum is coming from the AC power supply. I would try building a high pass filter. There is plenty of info on the internet on these. Below is one link. Hope that helps.
