7 Vintage Turntables That Are DESTROYING Your Records (And You May Not Even Know It)

📖 Get The Vintage Hi-Fi Buyer eBook. An 80-page field manual: https://vintagewatts.com Your vintage turntable is not wearing your records out, it is deforming them permanently, and the most prolific record destroyer ever built is the BSR McDonald changer, which held eighty-seven percent of the world market and shipped over two hundred fifty thousand units a week by 1977. A two gram elliptical concentrates its load onto a patch five microns by seven and produces roughly four hundred megapascals, while PVC starts permanently deforming at about a hundred. RCA engineer J.G. Woodward proved in the Journal of the Audio Engineering Society in 1968 that the same conical stylus over fifty plays obliterated 20 kHz information at five grams and showed no measurable wear at one and a half. You will learn why pressure rather than tracking force decides everything, since Hertzian contact pressure rises with the square of the reciprocal of the tip radius, so halving the radius roughly quadruples the pressure, why the linear tracking decks are the one to check tonight, because the Technics SL-Q and SL-DL series and the Sony PSLX deflect the cantilever against one groove wall when hardened grease and a stretched belt stop the servo keeping up, and how the BSR verdict is only half deserved, since restorers confirm a properly set up one will not damage records and it accepts an Audio Technica VM95E at two grams. The video covers Garrard's SL65, SL72 and SL95 where the arm is fine and the stack is the problem, the Collaro Conquest at ten to eleven grams with a fixed counterweight, console stereos at four to seven grams, and why a chipped diamond does more damage than a changer.
