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.
I’ll add my voice to those who recommend an outer ring. When I got one I sold my vinylflat right away. It is far easier to use than any reflex clamp, and does the job better. Moreover, by adding weight to the edge of your platter it will add flywheel effect and increase SQ for that reason alone. I use one with all records, warped or not. |
If a research is done into using a Peripheral Ring, it soon becomes apparent that additional to the intended benefits of the increased inertia, the impact of the weight on the LP, and the reduction of the warped form around the rim, has shown, if the reports are accurate that new levels of quietness are achievable during the playback when the Peripheral Ring is present. Not all TT's can utilise a common design of a Peripheral Ring, so it is always best to check if the TT is compatible with the design being selected. One such design change could be the need for a shallower depth weight or a chamfered edge to a weight.

@dekay , nice thinking. The trick is there can not be any temperature differential across the record or you will make warps. Will a heating blanket and glass panes work? Sounds like a nice experiment to me! |
I just had a look at the Furutech unit. It is the same unit as the Orb with a different dress on! The Orb is not sold here any more by license agreement. Lets see...$1150...$3270... nice racket. I'll follow @lewm to eBay. |
