I wanted to post a follow up to the previous comments. I took Johnbrown's advice and contacted Steve at the Analog Dept. He was great to deal with and he had a protractor on hand for my 12.5 arm. He sent it the next day and I received it a couple days later.
I spent about an hour with the protractor yesterday. Definitely a fussy process. I had taken a fair amount of time several weeks ago setting up a new cartridge using the VPI instructions, and I was convinced that I had it pretty well dialed in. When I started using Steve's protractor it quickly became evident that I was off - and by quite a substantial margin. I probably moved my cartridge back in the head shell at least 1/16 of an inch -likely just shy of 2mm??? Once I did that it was just a matter of fine adjustment to align the two primary points on the protractor. The cantilever on my cartridge (a Dynavector XV 1s) is pretty exposed so care is required, but it made it easy to set the zenith. I then went through the tracking force, lateral, VTA, rechecking, etc.
As soon as I put on the first record I must say that the change was awesome! Clearly, the set up process using Steve's protractor definitely made an audible difference - and for the positive. Everything is better focused and sounds much cleaner - less distortion I presume. Anyway, well worth the hour I spent on it.
Johnbrown - thanks for pointing out this alternative. I don't know how the results would compare with a Mint, but it's definitely a step in the right direction.
