Dear @ateal: forget what Raul advised you about Vdh or Northwest.
Look at your AT 180 stylus or rather cantilever. Only an aluminum
cantilever (tubed) can be glued on the restant of the original
cantilever. All present boron cantilevers are rods so the only way
to put this kind of cantilever on the restant of the old is to use
an aluminum tube as bridge between the two parts. Retip with
boron cantilever + whatever stylus cost +/-500 euro . With Raul's
and chakster advices you have no idea what to ask either of them.
How can you give whatever order to them with advices which only
assume that both retippers can do ''something'' with AT 180?
BTW the new boron cantilevers are not only rods but also thicker
than the original (tubed) boron cantilever by AT 180. Considering
the fact that an new AT 180 stylus is impossible to find not to
mention eventual price you already have the best solution possible.
But if you own whatever MC cart in need for an new stylus and/or
cantilever you can then ask both retippers for the involved price
(grin). MC's are different animals in this context.
