Dear chakster, You need to be exact in description of what Axel
deed. As I described elsewhere the (boron) cantilever in the
original cart is glued in the round magnet on the front side and
the tension wire on the back side of the same magnet. Behind
this magnet an round rubber ring is fastened as suspension.
To put a new cantilever in this construction either this new
cantilever must be glued in the magnet or an aluminum tube
must be put on the rest of the original cantilever and new cantilever
(solid kind) glued in the front side of this aluminum tube. Many
MC carts have such aluminum tube in front of the so called ''joint
pipe'' on which the coils , the suspension and the tension wire are
fastened . There is no way to change the suspension (aka the
rubber ring) without removing the whole cantilever and tension
wire from this construction. The problem is to do this in reverse.
To get the tension wire back in the stylus tube, to adjust and
tighten the (tension) wire.
BTW those SAS styli do have tension wire. The old Mori who
invented the 8 form coils (XL series Sony's) and was the first
to use the ''potting method''' inside the carts to prevent
resonaces is the guy who made (make) those SAS styli.
