Sudden problem with turntable


I have a rega p5 with a ortofon black. it used to sound great. yesterday i put on a record and it sounded terrible, really muddy. My knowledge of turntables is very limited. Is it possible that i damaged the stylus? Any suggestions as to how i would determine what happened?

Go to Vinyl Asylum and download the best protractor for your arm, put it on your table and follow the lines it's easy. If you think it's low on oil maybe from shipping don't use it till you top it off, look in there with a flashlight. First thing I would do find recommend tracking force for your cartridge and see what your tracking force is set at, to much force will dull sound. If you don't have a tracking force gauge make the arm float with the counter weight,set dial to zero without moving counterweight, then turn counterweight to cartridge recommended tracking force. Just be careful of not damaging needle while making it float. 

I'd vote against that last suggestion. You can get a surprisingly good digital stylus force gauge in 2 days or less on amazon for about $11. Cheers,

Could it be that the suspension on your cartridge has given up the ghost and collapsed, and (at the worst) you're just dragging along on the cartridge body?  
Bpoletti I can take a look. I know the cartridge isn’t dragging but how would I tell if the suspension is sagging. I am ordering a digital stylus and jewelers loupe and have also downloaded a protractor
