Ateal, What do you mean with VdH ''boron tube'' and ''suspension
upgrade'' for $ 750? Assuming some hazy ''upgrade'' without precise
knowledge what you are talking about is curious ''advice''. The
suspension by AT styli consist of the ''rubber ring'' in front of the
stylus holder + tension wire inside the tube behind the cantilever.
The whole stylus/cantilever construction is fastened with the small
screw inside the stylus holder. No retipper whatever can do anything
to ''improve'' suspension by AT styli. A boron tube can eventual be
glued on the restant of the old cantilever but ''above'' what can
such boron tube be glued if the whole cantilever is broken of?
Guessing like Raul and chakster do is not an responsible way to
give advices. There is no shame involved by confession to don't
know. For Raul and chakster obviously a big problem. Do you
want to join them in this attitude?
