AHAHAHA!!! the Horror!!!

A few days ago I rearranged by system such that my Lp12 was positioned in front of a large bay window. Yesterday was quite sunny, and I suspect the sun has warped a new record I had on the platter (which had been left there all day).
On sight, the record is still flat. But, I can see the stylus (and hence, whole arm assembly) move back and forth quite violently twice each revolution. A staticky "swoosh" sound can be heard twice each revolution as, I suspect, the stylus is violently run against the inner (and then outer) wall of the groove during each pass by the affected area.
Previously, the record was fine (no staticky "swoosh" sounds).
a few questions:
1. Does this sound like "warping" to you?
2. Will a smoked dust-cover protect my vinyl from the sun?
3. Does Linn still make a Smoked dust cover?
4. It could still be 70's sheek, no?

Hi Justin:
To answer your questions:
1. Yes, sort of. The vinyl probably got hotter in one area and 'stretched' in the lateral plane.
2. No but it might provide a better environment in which to cook the vinyl more evenly ;-)
3. No.
4 Nooooooooo.....
Best Regards,
Mark Dunn

Two panes of glass and a WARM oven will sort out the record.
Try about 30 mins, but keep checking.

Smoked will not help I trashed a record in a similar way many moons ago with my rega, that has a smooked top. Face it you are going to have to move it!

I too lost a classic Wire album by leaving on the deck in the sun.
You just have to tidy up after you have played the side, and put the record back in the sleeve.
The panes of glass in the oven sounds worth a try.
I used two pieces of wood, with the record in a paper sleeve in between, with about 100 recordds on top of the sandwich for a while. It made the disc just playable.

I once had a record that skipped like crazy, but it didn't skip on anyone else's TT, including the one at the record store. It turns out that one of my cartridge wires was hanging down slightly below the level of the stylus, where it could catch a very minor warp before the stylus did, thereby pole-vaulting the stylus out of the groove. Make sure none of your wires are drooping.

What temperature for the oven please?
I have two Cowboy Junkies albums which were inadvertantly left in a car in summer, and are now almost right angled! It would be great if they could be rescued.
Thanks,
Steve

100 C, and check every 5 minutes until it's flat again.
I've tried putting warped discs under heavy weights for days and it doesn't seem to work.
Gentle heating is much more effective.

Mu problem is more of a "horizontal warping". The record is perfectly flat. But it plays like the spindle hole was cut horribly offcenter.
Anyway, I'm just going to move the whole system out from in front of the window. Too bad, because now I haven't enough room for my TT stand, which means I have to put it on top of the equipment rack (which is shite).

Just off to put the oven on now!
I had already tried the heavy weights myself, without success. The vinyl seems to have a distinct 'memory' of the shape it ends up after heating.

I'll give that a go on one of my Zappa's that I bought s/h - it's warped badly, and weights etc. had no effect.
Sounds like just the recipe (sorry!)

Hope all is well. You could try a fairly cheap solution - venetian blinds. I use them to keep direct light off a bunc of stuff. As long as they are facing upwards the light gets difused and this seems to minimize probs.
