I would hate to set VTA for that record. There is a company that makes a record flattening device that one of your local audio shops might have. Not to purchase but as a service they might try to flatten it for you.

The Furutech DF-2 LP Flattener might help flatten it. It cost $2,170 which is why I did not think you would want to buy one. I had a local dealer with a great record cleaning machine and they would charge $.50 an album. Maybe you could find a dealer who might flatten it for $1 or 2.
