Depending on what you did to clean it up, I may or may not leave that,
but just about everything else I would leave to the mastering engineer.

watch the low end, both volume and phase.

I would make the mix slightly brigher than for cdr as vinyl makes thing warmer...my husband did a 7 inch with his band and that was a problem for them!

to master for vinyl you need, among other things, a lathe. i'm assuming you don't have one. i would advise against having some jack ass at the pressing plant cut your record.

hire a mastering engineer.

Seconded.

If you don't have a lathe, have never mastered for vinyl before, then get someone who knows what they are doing to do it. (and dear lord please tell me that you weren't going to take the tape and make a CD-R to send to be mastered into vinyl. Maybe I just misunderstood the title of this thread.)

A friend of mine had a spiral in spiral (double groove) or whatever done by http://www.aardvarkmastering.com/ and the sound was excellent.

Lot of good places out there. Isn't Bob about to get one up and running in the Chicago area?
