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

If you've removed the cartridge and you're adding weight, you'll have to revisit ALL the adjustments. To get it correct, the VPI table and arm take a lot of time and care.

So I got brave enough to install the headshell weight. Even though it was my first time doing any adjustments, I took my time, watched Fremer's DVD and thought I did a good job.

I have VTF at the high end of the cartridge recommendation. I adjusted Azimuth and even lowered the arm height (looked like it was a tad higher at the pivot).

I used the VPI jig (don't have a mint tractor yet).

However, the sound is rather harsh. Highs are thin, metallic sounding and (I think) distorting.

Can someone suggest what aspect of the setup might be off?

Thanks!
