Unstable Tracking Force Conundrum- a ghost in the machine ?

[worrasf]

Might be obvious but I assume the sleeve is fully on the arm and that the weight is towards the rear of the sleeve. Ie you don't have the weight forward and the sleeve hanging off the back....

I’m not sure I understand.
I have it set up as per the photos here on Hugo’s website;

It can’t go the other way around as then the VTF scale would be unreadable

Stephen look at the photo of my TK850M, I believe it uses the same weight, you can check this with Hugo, as you can see you can slide the weight to the rear and still have the VTF scale as it should be. As I said my LP-S and the Timestep ebony head shell is pretty close to the limit for my arm.

Agreed and as Adrian says, the counterweight is made up of two sections, let's call it a sleeve that slides onto the arm and the weight that rotates around and along the sleeve. I am asking if the sleeve is fully on to the arm so that the whole assembly is secure.
I know what I mean but let me ask a different way, is the end of the tonearm flush with the end of the counterweight assembly?

Yes, the entire sleeve is on the arm and pushed until it clicks on the little bump on the arm tube - freely rotates. I have the large part of the weight at the rear (with the grub screw) and the smaller component slid forward on the sleeve. Sorry for bad photo

Yep that looks fine. How heavy is your cart and headshell as I'm balancing an SPU on mine, admittedly it's an 850L but shouldn't be wildly different?

[worrasf]

The combo causing the issue is 28.5 total.
The Brier/FR which is fine is 25.3

Well my SPU is 30g and they should be able to handle 35g, is your 28.5g measured by you?

Yes, on a digital balance (not the one I use for setting VTF)
