It wasn't bad before, but since I'm able to play records again, I'm having problems with my platter bouncing, or more like shuddering, during playback. This causes the cartridge to bounce with it and skip across the record. It never used to do this. My music today was not loud at all, so it can't be from the speakers. And I put the lid down and walked away from the table, and it still was doing it. What is causing this? I was shown some ideas to help reduce vibration on this table, which I may implement. But I'm not sure they will help much. I was shown a base board for better damping, a better platter matt, and use of possibly some cones on the bottom. I don't know where the platter is picking up the vibrations, but it almost seems like its coming from the table itself.
