How many grams weight for mm cartridge?

You may never seen Grace F9 cartridges (F-9F, F-9L, F-9U, F-9D) tracking force range is 0.5 - 2g. I agree that 0.5 is too low, i would say 1g minimum.

I was a Grace dealer for many years and have owned several of the Grace cartridges, (actually I currently have a couple of F9E carts).  I have also setup MANY Grace carts through the years.

According to the F9 series manual which I just looked at, Grace doesn't give a range of tracking force, they recommend 1.2 grams.  So the .5 grams is not with a Grace F9 series cart...sorry.

@chakster...there are actually (2) pdf’s on Vinyl Engine. The first one, (Farsch) says 1.2 grams across the board, except for the F9P which is 2.5 grams.

The second pdf, (Alec124c41) shows the .5 to 2.0 range.

I have the actual owners manual from the F9E cartridge box and it says 1.2 grams, no range. I also just checked my dealer binder for Grace and it also says 1.2 grams. I have a pdf of the actual owners manual I can send.

Not sure when Grace changed the info, but again, .5 grams is way loo light for the F9 series of carts.

What cartridge do you have? Most carts will have a "range" of tracking force. I have always tracked most carts towards the higher end of that range.

I have setup hundreds and hundreds and hundreds of turntables and have never seen a cart that tracks at .5 grams.  I agree you can do a lot of damage tracking too low.

Would be nice to know the exact Shure model you have. Most of the V15 type series, (II, III or IV) track best around 1.25 and some of the replacement styli for these track best at 1.50 grams.

If it happens to be a V15 VxMR, then 1.7 would be just about right.

I doubt that it still has the original stylus on it. I bet it’s been replaced. I would try 1.4 grams. That’s a good compromise.

If you don’t mind spending $50, order a stylus from Ed Saunders. I’m using one on my V15 Type III and it’s stellar. If you ever upgrade to a more expensive table and arm, keep the V15 II and buy a Jico neoSAS/R stylus for it. Now that’s heaven!
