You do not need to adjust the height of the adjustment screw as that would change your azimuth. Once you have the azimuth where you like, do not change it.


Could the same be achieved by adjusting via the counterweight and not the lateral adjustment weights?

As above, or use the counter intuitive if you have one. IME, the side azimuth weight adjustment provides the most precise adjustment.

If you are referring to BillStevensons's $135 price I think he was referring to the fact he thought it was $15 worth of parts, so the $135 was the perceived improvement markup. Odd logic, but I can follow it. I've never seen the part in person, but from the picture and the limited quantities we're talking here I think it costs more than $15 to make them. They are made in the USA, after all, not China.


I would gladly pay more for USA-manufactured goods vs China goods.

Thanks Brf. I would rather use the counter intuitive as I do have one and for me personally, I think it would be easier to work with than the side weights...but I will look into the side weights too as an alternative. Just need to get my Lyra Delos back from Japan to be able to play with all this fun stuff which is now two months and counting... :(

Using the side weights rather than the Counter-Intuitive has the advantage of not risking messing with tracking force.

Thanks - I don't think my VTF should be affected as the counterweight is on nice and tight and I support it by hand when I am making those fine adjustments with the CI. But, I will also look into the side weights and appreciate the recommendation. ;)

I did this yesterday and using the side weights is much better. Moving the CI, even with a steady hand, can change the VTF. Remember we are measuring tenths, or even hundredths, of a gram. It does not take much to change VTF. There is no good reason to risk it when the side weights will not change VTF at all.

As Harry politely reminded me, with the dual pivot, the SS CI is not needed.

Some of the older VPI tonearms have fixed non-adjustable side azimuth weights, therefore, some user may choose to use a SS CI to pre-load their dual pivot as oppose to using the main counter weight.

It is for Vertical Tracking Force (VTF)!
