I did watch the Lederman video yet again and took millers advice and put on a record that has a demanding passage at the end. There was breakup in the left channel so I made small adjustments until the distortion was minimal and both channels were relatively equal.
Perfect!
Analog playback is far from the black magic everyone makes it out to be. Its actually really easy to understand, at least once its explained. Ledermann I think is even better at this than Fremer, maybe even as good as Miller! Almost! Ha!
Anti-skate is just one small aspect of perfect LP playback. If you listen close, want to get the most, and are willing to try things like this then you are in the most rewarding niche in all of audio.
So where you are now, you've pretty well gotten rid of all of the worst most obvious mis-tracking. Your rig is sounding a lot better now. You may even notice it sounds better even in places you never thought it was bad before. That's the beauty- you fix one problem, you notice benefits well beyond. Huge side benefit, you've learned to hear - and understand it. Take this same approach with the rest- VTA, VTF, etc- learn to understand both the mechanical aspects as well as how they sound, its really hard to overestimate just how much better you can go even from here.
