What would be the purpose to extend the connection? It makes more sense to have a direct connection from the tonearm to the reproducer, like the Phon-arm. I did not find any patent info on this Keen attachment.
If this is the same Keen as the Keen-O-Phone remember some of his machines had a long coil of tubing at the end of the tone arm, supposedly to provide better sound.
