Do you have records that are warped? We may be able to flatten them with our Orb Disc Flattener DF-01IA: the vinyl is gently heated and a uniform pressure applied over two hours then slowly cooled down over another two hours, to return it to its original state with no effect on the sound quality. $10 per record. Leave it with us overnight and it'll be ready for you the next day!
Now it won't always work, or may only reduce the severity of a warp, particularly on rims - and should not be used for heavy records (over 180g) or flexi-discs - but we won't charge you if it doesn't.
