Furutech Vinyl flattener or the ORB ?

Yes.  Orb make all record flatteners globally and OEM them to Furutech and Air Tight.

I have owned the Orb DF-02 for around 7 years and it has worked flawlessly.  

Orb have the DF-03 now, but you may be able to get NOS of the DF-02 on ebay.
Buy direct from Japan - All you need is a step down transformer.

highly recommended

Hi whart

Yes I do give some albums more than one flatten session.  I generally use the 2 hour timer or the 2.5 hour if it looks a little more dished than normal. some warps which are localised on one area will need a couple of flattens.  I will generally let go overnight, then cook again while I am at work.  Does not happen to much these two days.

  the flattener will work perfectly on any dished lp or mild warps.  Any warp that has caused the grooves to be deformed cannot be fixed. The flattener only flattens, it can't move the grooves forward or back when they are deformed - have to throw those out unfortunately.

  You will find some GZ pressings of the late 2000's and early 2010's will actually fry in the flattener as GZ decided to change to some POS soft vinyl compound.  They don't do that anymore.

cheers
