Is my Stylus damaged?

You wore in a deeper runout groove, that’s about it. Next...

I seriously doubt any damage done. 

Fully Manual TT: I tried some inexpensive after-market lifters, no success, then bought this excellent auto-lifter

love it, however, you need room between the edge of the platter and edge of the arm mounting plate. Some TT like my JVC, many Denon's have a wide rim around the platter, reducing available space for placement. Some have enormous arm plates.

It fit between my JVC TT81 Rim and my long arm's small base, but no room for it between my 9" arm's base and platter edge because the shorter arm hole is closer to the platter, reducing available space.

It should be OK.

jili12, 2 hours? That's nothing. I left it running all night once! The cartridge is fine and no I did not cut through to the other side. 

Well, thanks to all for your comments.  It sound OK so I guess it will be fine.  Have not been able to find tone are lift that will work with my Turntable, it is a Rega RP8.  Any suggestions?
