warped lp's


Recently purchased a sealed album but it severly warped. Does anyone know of a way to fix it?

Thanks!

It plays but not so well. I am more worried about the effect it will have on my table so was looking for a way to fix it if possible.

Am sure this won't be the last warped lp I buy and to tell the truth I did not pay much for it so throwing it away would not kill me. Had I paid 30 bucks for it, as I have on others, I might be a bit upset.

I did find some ideas as suggested by Bdgregory(thanks) but am still open to suggestions from others who have tried to fix warped vinyl.

So, as stated earlier, any info from persons with experience in this matter will be appreciated
I purchased 2 granite tiles at home depot over the weekend and plan to try to flatten a Ron Carter LP I bought used which has a terrible warp in track 1 and won't play. I'm going to try the procedure in the posted thread in the next day or so. I'll let you know the results. If it works, I have a few others - one of which is my new Portishead 3 that while it plays, is a little hard to track.
Thanks be intrested to know how it works out for you. I buy alot of lp's on audiogon and elsewhere and am sure to end up with more warped ones. Thats the chance I take buying sight unseen. Most of what I buy it in great shape.

Appreciate your input and good luck with your project this weekend.
