How warped can you get?


Ok, I should have looked closer at the LP before buying it. I was lifting a newly purchased copy of Renassiance Novella off of my cleaner and I noticed that the middle lifted quite a bit while the edge was still down. The surface looked really clean with no noticeable scratches so I decided to give it a test spin. I swear the cartridge is oscillating 1/4" in the verticle, but the playback is really good. I mean, it would be pretty hard to not to notice if Annie Haslam's voice was being distorted. I don't dare take the covers off of the woofers and have a peek.

So, I have to ask what is the most warped record you play successfully on your TT?

I have an otherwise excellent copy of a John Klemmer Direct-to-Disk recording, that is warped like a potato chip about 3/8". Even with my record clamp, it is a nightmare. I can track it, but at the outermost groove, at the lead-in, it sometimes causes the stylus to leave the record slightly, but it doesn't skip. Once it gets in about 1/8" into the record, it plays well, even though the arm looks like a small boat riding the waves of the ocean in a storm. I keep this record, because it has some of the most excellent recording quality I've heard, and it is expensive to get another copy. I don't play it often, but sometimes I just get in the mood to hear it. This is the worst one I have encountered that I even tried to play.

Anybody ever successfully flattened a warp? I've read posts about putting a disc between two pieces of glass in a 130F oven for ten minutes or so. What do you think?
