    I'm using a AT-PL120 & Pioneer VSX-D514 receiver, for years I keep getting this kind of click or flick sound, not a hum per se. It's not audible when the record is playing (only in quiet parts). is this a grounding issue? I don't see any option on the 120 to ground or my receiver

    Apologies if this is a dumb question

    Clicks and ticks almost always strike me as being a physical bit of interference, not necessarily electronic. Turn the receiver off, then start the turntable without a record on it and listen to/near the platter. Next kick the speed up to 45. Does the ticking go faster?

    it's def not ticking when receiver is off, the sound im here is almost interference. Not a click or flick say on a scratchy record or something. I'm wondering if a Isolation Platform would do the trick? as my LP120 is on top of my receiver

    I've also tried hooking the record player to different inputs and still the same flickering sound , but again when I turn on the input that my mac is hooked up to, no flickering sound, quiet when there is no sound

    Does it happen even when you have no record on the platter? Any way you could record it?

    That really sounds like vibration being picked up by the cartridge and amplified. Is there anything nearby that could be transferring vibration to the table, like a fan or similar?

    Check the RCAs too. Unplug one, then swap and see if it’s coming from both channels. Sometimes a short can have that flickering effect.

    I would also try plugging the receiver, TT or both into different outlets and see what you get.

    this I dont think is an issue due to the input working fine without flickering for the mac

    Did you get the noise with only the red cable plugged in? If you move the white cable between the left and right channels does the noise follow?

    Oooooh yeah. And if you have a dimmer switch in that room, unplug everything and go get a drink.
