JMW-9/Cartridge Problem

I had the opposite problem with my Grado Reference Cartridge.I had it tracking at one point way over spec. at 2.6 grams with my Morch Arm.I realised this when I bought the Shure Precision Stylus Force Gauge SFG-2.
In my case my arm comes with 3 different counter weights
so I was able thru trial and error finally able to get it tracking at about 1.6 grams.I had on to large of a counter weight to begin with,and used my medium and small counterweight to balance things out.
My weights are a bit forward closer to the pivot ,But everything is working fine with my VPI MK3 Morch UP-4 Combo.
I'm not familiar with your arm.Do you have the option of using a heavier counterweight?Your cartridge weighs the same as mine so this may help alot.If not 1 or 2 small lead spacers between headshell and cartridge should help.

Will try to get ahold of vpi today to see about a smaller weight or spacers. I'm using the same shure scale.

I am perplexed at your difficulty. I have the same cartridge & arm and have had no problem dialing in anything between 1.5-2.0 grams using the standard dropped counterweight that came with the turntable/arm from VPI. No additional weight was required. No offense pointing out a seemingly obvious thing, but did you check to make sure all is ok with the Shure gauge? I have had the pivot point get sticky & bind on ocassion.

I had to order another weight than the standard for my Dyna karat.

I just installed a Clearaudio Sigma (4.5gms) on a JMW9 the other day. Clearaudio supplies a lead shim to add in case the counterweight is not light enough for the cart. I don;t know if VPI makes a counterweight smaller then what is supplied with the JMW9. I know they have heavier but not lighter counterweights
