New Schroeder linear tonearm, any thoughts?


I noticed Frank Schroeder has a new linear arm without servo motors, pumps, etc. seems like a promising direction. Did anyone hear it at RMAF?

Sarcaher,

Thanks. I think I get how it works. Would love a video. Seems interesting.
The arm falls into a tradition that goes back to the 1950s- pivoted arms that are capable of 0 degree tangential error.

If interested there is an extensive thread with lots of photos and diagrams on DIYaudio.com:

The thread also discusses some of the issues with this approach.

The Schroeder arm shows up about a year ago on that thread.
I don't see any pictures depicting a tangential tracking arm. I only see pictures of their hanging on a thread/magnetic attraction version of a conventional pivoting arm.

What, if any, mechanism provides for tangential tracking?
