How best to eliminate LP warps


I own about 2500 LPs, and I like to think they're flat.  Furthermore, I espoused the view that warped LPs ought to be discarded.  But lately I have found 2 or 3 of my LPs that do have warps but sound too good and are too precious for the music recorded on them to throw away.  So I am in the market for ideas on how to remove warps.  I am aware that there was a device on the market that looked like a large waffle maker, to be used for warp removal.  I think Furutech made it, but I never see it advertised these days.  I am also aware of the DIY method of placing an LP between two glass plates and heating the ensemble.  The question there would be how hot and for how long?  Any suggestions are welcome, especially opinions on the efficacy of the Furutech.  Thanks.  Please no comments on vacuum hold down; I think it's a great idea but none of my five turntables has that feature.

No, if you read the print, even on @mijostyn ’s link, it says "no longer available for purchase". . . I only found it available for sale in Japan. You can find it on ebay.

The previously sold $1900 Orb was the cheap one! The expensive one, that’s still available for purchase in the US in the Furutech DF-2 for $3275!

The Orb units work.  My local record store has one and they have flattened a number of records for me with it.  I've been thinking about getting one.

Here's where to get them in the US - Record Flattener – Mockingbird Distribution LLC

 

Orb Disc Flattener at Acoustic Sounds recently back in stock. I couldn’t get a reply emailing Mockingbird.

@big_greg , Great find Greg and less expensive! $1150.00 @;lewm Have a look at big_greg's link. I sent them an e-mail asking about availability.

@mijostyn @lewm @big_greg 

Mockingbird no longer sells them.  I already investigated this:  they are only available from Japan as 100V.
