VPI 10.5i - Which armwands do I own?

Call or e mail Mike at VPI. He'd be more than happy to help.

It looks like you have an aluminum, and a stainless steel arm wand. The sound is the same (it looks like they are both wired with Valhalla). The stainless steel one is newer. They changed it to accommodate more cartridges which require more heft. They are both set up the same way, and if you are using either Benz or Dyna cartridges, they both are equally good.

You say the one with the "slanted" azimuth ring can't be adjusted. I have one with the same azimuth ring, and it's adjustable. Did you loosen the two set screws holding it in place? It's still stiff to turn with the screws backed off, but it will move.
