930turbo, you might want to experiment with other protractors. VPI uses a proprietary geometry on its jig, which (iirc) gives classical music the best ride. I’m a jazz fan, and prefer Baerwald. YMMv, let your ears be your guide.

How about the protractor that came with the 10” 3D to setup a 12” Fatboy as a replacement arm? Thx!

It won’t work due to fact that the two arms have a different effective length.

Thanks for the quick response. I just received my new 12” Fatboy. Unfortunately, I will now have to wait until a new jig arrives to set it up. Disappointing since VPI was told that it was a replacement for a 10.5 3D arm.

Furthermore, the new arm did not include any installation information/instructions and the arm is very wet (?). I have reached out to my dealer but this experience has left me very disappointed.

Quick question, is the 12" Fatboy replacing a 10.5 tonearm and are you using the same VTA base and position as the 10.5" tonearm?

I believe this is at least the third report of a wet Fatboy. Hopefully VPI can resolve this issue.
