Fell asleep while TT was running with ortodoncia black cartridge!

There is a nice device for those who prefer to fell asleep while playing record: Audio-Technica SAFETY RAISER. It will lift up your tonearm when the record is finished. Buy it and sleep well. 

As others have said, no harm done. When I was a teen I would fall asleep in bed with my Koss headphones on. Table had been spinning all night. I eventually bought an arm lift marketed by Monitor Audio. It was under $20.That was in the 70's. These days you can get a Q Up arm lifter on Amazon for $40.

If you have room, you might consider buying a vintage turntable with the auto lift feature. For $275.00 I purchased a Harmon Kardon t65c for late night listening. In its day it was nicknamed the working man's Linn Sondeck. I probably use it more than my Manual Table.

I have a couple of automatic turntables, in part for that very reason.  Music really relaxes me at the end of a day and I sometimes find myself waking up on the sofa after a listening session.  I have a JVC QLY66F in my main system and a Realistic LAB440 in my bedroom.  They are both decent performers, the JVC is better than the MMF 5.1 (which I have owned) with a little bit of internal damping and better feet.  The Realistic table is surprisingly good, but not as good as your Music Hall table.

My CEC TL2 has never had that problem
