A couple of years back I found a sealed copy of the Timothy Wilson Lp in a Boston record shop for a dollar - nursed it all the way home and upon opening it - it was warped - so looked at a record flattening service on eBay for a tenner - he is still on there - based on Lincs - anyway I send it off - it arrives and he messages me back saying - I can try but it’s the worst warp he has ever dealt with and it may destroy the album completely - I have nothing to loose but a dollar !
End result he gives it a go and it’s perfect ! Best tenner and a dollar I’ve ever spent !!!!
