Any Warp correction LP services available ?

G_m_c, I have heard of the same trick, as well! The record is placed between two sheets of glass in the oven, for an hour or two. I would put some weights on each of the four corners. REMEMBER THAT CUT GLASS WILL HAVE SHARP EDGES, SO HANDLE THE SHEETS WITH SOME TYPE OF GLOVES!!!

Certainly, a cheaper alternative to the two machines mentioned in this post.

Albert,based on the pics of your room/home and system tastes I'd have to volunteer you to "go For It",and report back.Me?Well I just finished paying off Rutgers U. with their last payments,for my 2 kids.Whew!!I,also just "Blew" a load on some ultra pricey CCa's for my phonostage,and would like to take a summer vacation.I would totally trust your report,but,make sure you follow up the tubed crossover,as promised,ASAP!!Best of luck!!

Here's one big enough for an LP and so far, going for less than a hundred bucks.

Seal Press

I've used the glass plate method with only moderate success. On some LPs the bead would heat up and deform enough to allow the glass to contact the grooves before the record would flatten out. This would leave a flat spot in the grooves and ruin the record. I always wondered what would happen if pressure were applied first, but was afraid to try clamping the glass for fear of breaking it. It seems to me the Seal press would be great, as long as you're patient enough to get both the pressure and the temp correct.

As an aside, I had my best results at 200 degrees, and any glass cutter can sand the edges of the glass plates so you don't cut yourself.

Using the glass plate method (I used 2 pieces of 1/2 Laminated glass) it would often take an hour or two at the low heat. I never placed weights on the top plate for fear of crinkling the lp. I feel it is better to let the lp heat up very slowly and cool down over night before removing the weight. One note of caution for any process, some vinyl is of poor composition and might self destruct. I offered to straighten a warped early, off lable, Lou Reed and John Cale live Drella lp. It completely melted out in areas, blurring the grooves. It was clearly substandard vinyl. The fellow was very understanding. This might bring up issues of liability....
