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?

Awesome! Thank you so much for the picture, Jfrech!! Happy to know that you're enjoying this brilliantly engineered tonearm designed by a genius!

I am wondering how the effective mass can be so low as "14 to 21 gm", which was stated somewhere above. If you think of it, the stylus/cantilever is swinging the whole enchilada all the way back to the stationary pivot that bears the rotating pivot apparatus. Thus the effective mass would be the additive of the masses of the swing arm, the base and pivot assembly at the tonearm proper, the counter-wt, and the arm tube/headshell. But perhaps that is not the proper way to think of it, or perhaps the LT components are made of extremely light weight materials.
The error in my thinking: Yes, the effective mass is high in the horizontal plane, because of all the paraphernalia necessary for the LT function, but it is only affected by the masses of the arm tube, headshell, (cartridge), and counter-wt, in the vertical plane. Many tonearms are similar in that characteristic.
Hi, and this arm when properly set up (just once during installation) has a ever so slight tendency to want to move to the inner groove...a slight breath sends it on its way...if you have the stylus on a blank record...so not much mass or nearly any force needed for it to trace the grooves...
