I’ve got a 3rd meniscus tear from lifting my 80lb McIntosh MC2250 from a low shelf in a tight space. Watch 2 strong friends do it for you!
Some delicate things, like a TT, can go in the car with you. When younger (i.e. poor, moving myself) I always packed the sound system last, and remove/set up part of it first, get some music going during the pack/un-pack. Keeping an all in one boom box may be smarter.
