For some reason they mark the weight 10 (something) which = 1gm.
If anything positive has come out of this - my TT is definitely set up correctly now.
That is your silver lining.
By the way the stylus getting stuck, probably means those records are pressed on recycled vinyl. This may be a problem surfacing again. This got to be huge problem in the late seventies and early eighties.
They take old discs and don't bother to take the labels off. The paper comes to the surface and causes what you are complaining about. It gets worse over time as the paper comes to the surface. I have some LPs pressed in that era that are just about useless.
The best pressings were between about 1958 and 1972. Then the short term profit boys started ruining it for everyone, and caused the grief we are now in. It sounds as if they are still very much with us and no lessons learned.
