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?

Thanks for the photos, but I would really like to see a video of the arm in action, showing how the pivot point moves. Is there anything on YouTube?
On another forum I got a request for this to...will try and record something tomorrow...Thinking I need to find my tripod and clamp the camera to it...either a few pics or try the video on it...
Hi,

Here is a youtube video link from this past RMAF that "might" give you a better feel for how the Schroeder LT arm operates.

I also have the arm installed on my Beat TT and I would echo what John has said about the sonic performance of the arm. I've tried to describe as best I could what I hear with the LT arm on my system page.

Hope that helps a little.

The first video is fascinating. The second one does not really give a sense of what is happening.

I would think that for it to have truly linear (tangental) movement, the stylus must follow a straight line moving along the exact radius of the LP, theoretically ending at the spindle or center. It looks like this is accomplished by the base moving in and out and being hinged at two points and moving along an arch. But I don't see that the base moves the entire 5" or so that represent all of the grooves on the LP.

It's a very intriguing design and a difficult geometry problem to visualize. The bearings must be extremely silent and free of slop for there not to be any chatter considering all of the movement at the base where it can vibrate. Could Arnie or jfrech add some clarification?
