This may be a really dumb question but I couldn't find an answer when I searched so...
How do you go about setting up a second tonearm on a turntable? I've seen them with 2 or 3 arms but cant find info on how to set up the additional arms.
If you want give a spindle to pivot distance and we can work out how to set up a protractor. Or give an effective length and we can work the set-up that way too.
