Ive been cataloging every defective record I come across for two years now, mostly flea market finds and dollar bins. Last month I logged my 500th skip and noticed something weird: about 40 percent of them came from records pressed in the 1970s on recycled vinyl. It clicked that those pressing plants were cutting corners after the oil crisis, and now I check the deadwax for plant codes before I even pay. Has anyone else noticed a decade or label that seems to fail more than others?
