Default Schröder LT tonearm

Terrific images of the innovative Schröder LT tonearm. Notice there is NO offset at the headshell. Also notice the magnetic guiding system under the base plate. If I'm interpreting the pictures correctly, looks like a pivoting armature holding a magnet following a curved steel rod path and therefore no mechanical contact.

Frank Schroeder is one clever guy!

Classic ton arm with magnetic antiskating.

It has nothing to do with antiskating.

Default SchuchTronic & WKarlson

On post #61, I posted about a WKarlson tonearm that I am still not sure if it's a tangential pivot tonearm like the SchuchTronic arm. But there are striking similarities in using strings, round headshell, and aesthetics. Both look like Frankenstein but fun.

Compare below.

More pictures of the wacky SchuchTronic tangential tonearm from a German website.

Finally I understand the principle.... quite clever... as the stylus moves inward to the center of the platter, the magnet pulls the arm base following the curved metal, causing the pivot to change position

I heard that arm at Franks home.
It sounds awesome and is a perfect example how simple it can be.

Exactly. The clever thing is that it never had to use any linear bearing or any contact type of bearing, hence the low friction. The shape of that curved metal is crucial to the tangential accuracy, though.
