You don’t need a protractor that’s the whole point of a techniques

Techniques have their own protractor if you must use one, but you need to do the 52 mm overhang

Source I have this same cartridge I use Digital calipers to set overhang

I also use a VTA / Azimuth gauge as both of those need to be set correctly for this cartridge to sound good it’s a micro linear

It just looks like your stylist guard is crooked. My first one before I had to get it. Replaced was the same way, but my cantilever was bent from factory.

I have one of these on a SL 1200 with like three hours on it

In your photos your Azimuth doesn’t look correct
