warped platter LP120

Post by streetpussy » 13 Sep 2018 03:09

I know most platters probably don't spin perfectly straight, but is this excessive? It was worse before but for whatever reason rotating the platter slightly helped a bit. This seems to be as good as I can get it though.

The first video is the beginning of the record where it looks really bad and the stylus is bouncing/vibrating out of control and the second is towards the middle of the record where the wobble is the same but the stylus stops vibrating and just sways side to side instead.

VTA and cart alignment are spot on.

Probably should've just gotten a used SL1200 on craigslist for like $200 more.

From those videos it's obvious that the record itself is the cause for the bouncing/swaying.
I can see the warp in the record's reflection.

I don't think that platter "hop" looks excessive. Your record is definitely worse.

My LP-120 looks just the same as yours, and my Pioneer PL-71 also has a small hop to it.

Most platters do spin without bobbing up and down, this seems to be an issue with some modern turntables. It used to be the case that turntables were built to spin precisely, the exception being very cheap models like the Goldring G101.

These days it appears folk are assuming this is normal. None of my turntables have a wobbly platter,all of them over 20 years old, that would mean the platter has warped or the bearing failed.
