How many grams weight for mm cartridge?

The Grace f8-L’10 is also rated for .5 - 2.5g, along with other f8 carts. Below is a link to a Japanese sales brochure with the numbers clearly visible. This does not mean it’s the recommended VTF, only it’s possible range. In the owners manual it states the .5g is for perfectly flat discs, and the recommended setting is 1.5g.

The f8-c is rated .5 - 1.5 with a recommended 1.2g 

These carts were of course designed for arms like the Grace G707 and Infinity Black Widow, and why I'm currently using one.

The F9 is a great cartridge based on the F8 actually, improved and modified to work on a much wider variety of arms. That said, the F8 is a fantastic cartridge in its own right, and the better choice if installing on the above mentioned Black Widow or Grace arms due to its more suitable compliance.

The F8-C especially so, and in attempting to procure one ended up with the L'10 instead and now a happy camper. There's something to be said for using the cartridge actually designed to go on the arm you're using, and both designed and manufactured by the same company.

I can say it was a real ear opener lol.
