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?

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.
Lewm, I think that is driven by skating forces that arise as soon as the arm is out of tangent. If you'll notice the cartridge is mounted square in the headshell- no offset angle- which would increase said forces.
There's a little guy in there that moves it for you :)

It is the tracking force in tandem with the skating forces that arise if the arm gets out of tangent that realigns it. If you are thinking this relies on really good bearings you are correct!
