Cartridge for JMW 10

Carl,

The 5 gr.ZYX would be too light for the stock 10 arm.What I have is the stock arm without headshell weights. I obtained a light counterweight for the 10 arm from VPI. Its the same as the dropped CW used on the Scoutmaster model...but fits the 10 arm. Sheila took my stock weight in exchange, so it cost nothing to do. Without the lightweight part, I would have needed the headshell weights or the Silver Base option on my ZYX to balance properly.

Great solution Kehut.

AFAIK ZYX's optional silver weight is only available on the Airy 2, Airy 3 and UNIverse. JMW owners using lower priced ZYX's would have to get the VPI weights or, as you stated, a lighter c/w to increase their effective mass.

Thanks for the suggestion , guys. The counterweight seems the way to go.

Curious, Kehut, if you have run into this with your arm....The cartridge must be installed at the very end of the arm to get the proper position regarding the tracking protractor. This means that when I clost the dustcover, it actually taps the tip of the cartridge, unless I pull it forward a bit.I assumed I must have mounted the cartridge wrong at first, but several checks verify it's where it should be. I use the HWjr Mk4 table, ang gather the base is not designed for a cartidge like this, rather one with the stylus more forward so that there is clearance.
Makes one cautious when having a glass and spinning some discs, let me tell ya!!
Will get the lighter counterweight ASAP.
Thanks again.

I did indeed have this experience and called VPI. Harry suggested the lighter CW. He was very familiar with the scenario of trying to use a lighter weight cart like the ZYX and Dyna D172Mk2 on the 10 arm with the standard CW. The 10 with the standard CW is designed for cart weights in the 7 -12 G range any lower you will neeed to compensate for the weight balance as suggested.Any higher and you'll need the heavyweight model

The effective length of the 10 arm being what it is does indeed make for an interesting fit on your HW series table Im sure, especially with the cover!

Even on my Aries/JMW 10 combo the alignment jig when set in place puts the cart rather forward in the headshell for correct overhang, so im sure yours is correct also. The base of the Aries is larger..so the overhang does not look as prominent I suppose as the HW._ken

Spoke with Mike today at VPI, and he suggested BOTH the lighter drop counterweight and the 3 gram headshell weight. He said I would be better off with the counterweight mass a bit away from the pivot, contrary to popular belief, so I'll get that combo and see what happens.
