MAG-LEV audio ML1 - 9.2. Setting Up the Anti-Skating Weight; Anti-Skating Force Adjustment; VTA;SRA Explanation Revisited

9.2. Setting up the anti-skating weight (page 09, part 10)
You have to set the anti-skating weight on your
own as it is necessary for it to be packed sepa-
rately, to ensure the safety of the product.
The anti-skating force must be adjusted accord-
ing to the mass of the cartridge as follows:
Pro-Ject 9cc
For Ortofon OM10, use the 2
nd
groove.
Downforce Groove in the stub (10)

Hang the loop of the thread of the anti-skating
weight (8) in the groove of the anti-skating stub
(10) corresponding to the downforce applied to
your cartridge and feed the thread through the
loop of the wire support (9).
As you can see there are two different angles
serving the same purpose. VTA and SRA. These
angles are affected by the height of the tonearm
and tracking force. The height of the tonearm
raises the actual pivot point of the cantilever
(SRA). The higher the tonearm on the armboard,
the bigger the SRA and VTA. Changing the
tracking force changes VTA due to cantilever
suspension. With a lighter tracking force, the
cantilever is pushed up less and VTA and SRA
are bigger. In reality different cartridges have
variations in design and SRA can be around 85-
95 deg while VTA is 18-25 deg.
Refer to the image below if you need to
readjust the setting for Ortofon OM10. If
you are installing another cartridge, refer
to manuals from manufacturers of the
cartridge you wish to use.
