Here is what I would do.
Pull out the phono and preamp tubes and spray some electronic cleaner into the sockets...Deoxit D5 is a good one for that and don't worry about over spray as it won't hurt anything but try and get most of it into the socket holes..Then pull the tubes in and out a few times,the phono tubes especially to get the cleaner worked in.Lastly, you want to spray around the phono input jacks where your turntable plugs into.The phono voltages are so low that any electronic disassociation with those connections can be an issue.
I'm glad you love the tuner..I just saw that..Check your stylus pressure as well but do you have another unit you can hookup even if it's solid state? That will tell us if the stylus has an issue..Usually when the stylus wears,you lose high end and its starts to take on a harsh sound.Do you have a scale to check stylus pressure?

My father taught me to use pipe cleaners and alcohol on the tube sockets. Now I use Deoxit, but I think the pipe cleaners are still a good idea. I save the alcohol for when I listen, and I buy better stuff.

I was tracking at 1.9 grams and increased it to 2 and there was no change. I don't think the stylus is worn. If anything it may be the suspension.
If you have good clarity and the mids and highs are good on the phono,lets spray those tube sockets.Sometimes just pulling out the tubes and reinserting them can make a difference.Do you have another amp or receiver with a phono stage so we can rule out if it's a turntable issue or not?..A solid state unit will be just fine.
