Title: Cartridge setup question
Post by: aragorn723 on July 11, 2021, 03:14:52 PM
I recently got a London Maroon cartridge and am setting it up on a Uturn Orbit turntable (yeah, I know).  This is my first time installing a cart.  The alignment protractor that came with it says to point the arrow at the vertical pivot axis of the arm.  Not sure if I did that right, please take a look at the picture and let me know.  Got the tracking force set to 1.77g (London says to use 1.5g-2.0g).

That is correct for what the instructions are telling you to do.

Thanks for the confirmation.  Sounds like this alignment won't work, the stylus doesn't line up with the dot it's supposed to, and there's only a few mm of adjustment in the headshell.  I also have a protractor for Lofgren A, any reason not to try it?

I actually bought one of these, got it sitting at home.  Guess it's time to try it.  Shouldn't be hard to align the cart to this since that's what Uturn recommends.  All together, wasn't too hard installing the cart.  Thanks Paul.  Maybe I'll have to get a Eros eventually to see the full capability of this thing.
