Exposure to heat can cause the records to shrink - causing a wobble. This can be emphasized by the high compliance of a stereo cartridge. It causes the tone-arm to swing back and forth. This usually affects the beginning of the record but lessens after the first 30 seconds or so. Both tone-arms I use have a rounded area at the base of the pivot so that I can put a bit of back pressure with a finger to prevent jumping until after the damaged area has passed. Also a lower compliance cartridge like a VRII can help with a problem like this -Mickey -----Original Message----- From: 6295LARGE Sent: Wednesday, September 19, 2018 12:06 PM To: [log in to unmask] Subject: [ARSCLIST] Shoenberg: Gurrelieder Stokowski vinyl 78 M-127 tracking problems Hello everyone I never thought I'd have tracking problems with these beautiful vinyl 78s, but i do. I know they've been reissued on LP and CD, but, strange as it may seem, I need to have the 78's for transferring purposes. The styli are jumping. I've even tried with a .7 mil stylus just to see if it would track better. I tried playing the records at 45 and 33, but the styli keep jumping forward. It looks as though the grooves are jerky while the records look brand new. Has anyone ever come across this problem? Regards, Ben Roth PLEASE respond to [log in to unmask] Thanks!
