VPI Headshell weight question


So based on a recommendation from Harry (VPI), I purchased the 3g headshell weight for my Scoutmaster/Shelter 501MKII. It didn’t come with any instructions and it’s not obvious how to install it. Does it go between the headshell & cartridge or attach to the top of the headshell?

Also: I assume I re-adjust VTF so that it’s still within recommended range (i.e. Shelter manual) or is the whole point that I need to go over by 3 grams?

Thanks…

Between the cartridge and headshell. Rebalance the arm and apply the recommended tracking weight for the cartrige.
Depending on how retentive you are about these things, remember that increasing the thickness of the cartridge mounting can affect the stylus rake angle and stylus contact point. I assume you'll use your mounting protractor to remount the cartridge after installing the weight, so the contact point change will be corrected. A slight increase in the arm mount height may be called for as well to correct rake angle.
That makes sense. I've never setup a turntable myself, although I just bought a digital scale, I have Michael Fremer's DVD, and need to learn sooner or later.

I was hoping that this might be a good time to start if I only had to make 1 or 2 adjustments.

Thanks.
