From your original post a few years ago, there was not much love or knowledge for this old player. As far as cleaning and servicing goes, you would probably pay what the TT is worth to have someone do it.
That said, there is no bad place to start. Try it out and if the bug bites you, move up to a more current or well loved older TT and Cart.
I lucked into a Rega P3 with the Elys2 and with nothing else to compare it to and using the Phono section in my Luxman, I am fine for now and beyond.
What will more than likely happen, is all your quality gear will tell you that the old TT is the weak link. But again, you have the TT, you want to try and see if you get the bug, so why not just hook it up and check it out by now?
