The Aubert bridge on my fiddle -all maple, no ebony e string slot, is about 7 years old. The A string is wearing a notch into the bridge. Is this normal? I am getting ready to change the strings. Should I take the little tubing off the old E string and put it on the new A string, or get some of that violin parchment and put it where the A string will rest? Thanks,
I would try the tubing first as it can be pulled off if you do not like the tonal result. You may wish to fill the cut with a mixture of glue and fine sawdust and tailor it back to spec with an emery board or some fine sand paper before you glue some parchment to the bridge.

Don’t use tubing. It’s a tone-killer. Any good bridge will have parchment on the E. You can add it to the A as well if you want without it doing any harm. If the groove is especially deep, you may need a different solution, though.
