Tone Arm lifts at end of playing a record

Some thoughts, and likely force related - too light, so it pops out:

1. Some records can be different than others towards the end.

2. Check the tracking force (pressure on record) setting for your player & cartridge (e.g: 1.8g) - if you haven't yet make sure the tracking force is set properly - there are some youtube video's to watch. 

- I suspect it might be too low so can pop out.

3. Make sure your anti-skating force is properly set (usually this should match tracking force). Mine is slightly higher. 

Hope this helps, I suspect you've set the tracking or anti-skating force a bit too low so it pops out. 

@knock1 I'd imagine if his tracking force is way too light, it would also be more likely to pop out (I've seen this). It's likely the record though.
