VPI 10.5i - Which armwands do I own?

I just changed my cartridge and in doing so, had to adjust that rear counterweight for azimuth alignment. The last time I had to do that was about 7 years ago when I last put in a cartridge. That azimuth ring as I read between the lines is something new...that it can indeed adjust azimuth. In the older aluminum arms,one of which I have,\... the proper way is for rotating the rear counterweight....not a big deal.

Well sure, Stringreen, but that means every time you adjust VTF you have to RE-adjust azimuth .. and then readjust VTF ... etc. Much simpler to use the azimuth ring in the first place.

I find that even rotating the azimuth ring messes with the VTF on mine. And then resetting the VTF messes with the azimuth. It'd really be nice if VPI would key the counterweight to the arm on assemblies that have the azimuth ring. Even being as careful as possible, it's almost impossible to slide the counterweight without rotating it slightly.

I have a new cartridge due this week, I'm not looking forward to doing it all again.

JR_W....congrats on your new cartridge. You might have noticed that the rear counterweight set screw does not set into metal, but simply tightens the black plastic ring that's inserted in the weight..therefore....you shouldn't loosen the set screw to move the weight..simply force it slightly...if done with caution, you can adjust either the VTA or weight rotation. In addition....if you just want to lighten the VTA a bit, there is an internal adjustment weight accessible with a large Allen wrench through the hole in the back of the arm tube. By unscrewing that weight (it could be tight, but don't fret...use some force...) it could be used to easily fine tune the VTA.

I didn't know about the large allen screw in the rear of the arm, and I swear I RTFM! I saw the wrench, but thought I had adjusted everything that I could adjust without straying into the "void warranty if any other screws are messed with" territory.

That'll make it a lot easier to fine tune the VTF.

P.S. Thanks for the cart congrats, got a shipping notice today.
