I know this isn't what you want to hear, but you should learn to do these things yourself. Buy a good protractor and digital scale. If like me, your eyesight is shot, download the Magnify app to your phone. You will get a good view of the cantilever when adjusting your cartridge. Owning a good vinyl rig such as you have, you'll really want to do these things yourself. It's a little fiddly, but you can do it.
Quandry
About a year ago I bought a new turntable (Dr. Feikert Volare) and complementary equipment. I had it assembled by a local technician as I have two left thumbs when it comes to DIY. (I know this is not a good trait for a turntable owner to have.)
I’ve been dissatisfied with the sound for some time. But I recently discovered that by tweaking the anti-skating, the sound improved dramatically. I’m now wondering what other parameters have changed during the past year.
So, not being able to tweak those other parameters myself I’m thinking of hiring the technician to come to my home to work on it. Since it sounds so good now, I’m wondering if it’s worth the expense. (He won’t be cheap.)
