Turntable issue

I haven't had much luck finding an answer to this question so hopefully it's not something that's been asked a thousand times.

Yesterday I turn my preamp on, place a record on the player and I can hear every touch of the tonearm I make. It clicks when lifting it out of its resting position and when I screw or unscrew the record clamp this at is also very audible through my speakers. Also I'm now hearing a hum that was never present before.

I understand that the cartridge picks up vibrations and turns them to sound but this has never been something that was clearly audible before. I'v never heard siuns coming from my speakers when screwing the clamp on our off.

Thanks for any responses.

Thanks. I will try some of your suggestions. I was thinking it is a possible ground issue or a tube problem but wanted some others opinions. One of my tubes is looking rather black on the glass when I checked this morning. The other tube still clear. Sure would be easy if its a tube.

Only change I've made is running output to pc to transfer vinyl. Otherwise no other changes.problem wasn't there when I swapped output. Showed up later. Problem doesn't go away no matter the output either. I wouldn't think this has anything to with it.

Ground wire foing from the 5.1 to the tube box s is fine. No kinks and looks like it was taken straight from the box. RCA cables are signal cable silver ref phono cables. All connections are tight. All power cables are tight. I will try swapping cables first then try the ground wire from tonearm. Hopefully I have some time when I get home from work.

Thanks again fellas

Swapped the tubes out with a pair of reissued Mullards. Anyways mostly everything has gone away. When I tap the player I no longer hear it through my speaker, I cant hear the clamp being screwed...very slight hum when nothing is playing but only if I turn the volume up high.

Thanks again for all your help
