[78-L] Can vinyl be unwarped?

[Doug Pomeroy]

There's a company which advertises in Stereophile
magazine which carries a device which they claim
will flatten LPs.  The say it costs $18,000.00.

Vinyl stretches, so the usual warps won't fix at all, sad to say,? 
because you can't shrink the stretched plastic back into shape, so  
forget the heavy glass method for them.

For shellac 78's you can get plate glass from most any glass shop,  
sometimes hardware stores, but mostly they will stock the light stuff  
for household windows and that's too light, too thin.
