Hi Pani, As ''involved party'' I am reluctant to react at your post.
However I am well informed about ''retips'' because Axel Schurholz
is my good friend such that I know what their problem is. First of
all all cart producers get their cantilever/styli combo's from their
supplier. Except Van den Hul who also owns an retip service nobody
else does retip work. Anyway not the ''stylus only'' retip. This work
can only be done by specialist with long experience. So there are
only few which are willing to do this work. Retipping the whole
cantilever/stylus combo is much easier to do because the new
combo is ''simply'' glued on the se called ''joint pipe'' on which the
coils and suspension are (also) fastened. The problem by retip
services is the availability of ''parts''. In particular boron cantilevers
and micro ridge styli. So in your case you need to search for a
retip service which offers both. Axel was not able to get other
than Shibata styli , had more work than he could manage, so I
investigated for him in Japan by two big jewel companies there.
Neither ever answered my questions while J. Carr whom I
asked for help warned me that those comapny are not, say,
very helpful with styli.
Because Axel retired I searched for one other retip service and
found ''Expert stylus'' in UK. They do ''stylus alone'' retip with
their own stylus called '' Paratrace'' which is similar to micro ridge.
This work is done by their engineer with 40 years experience.
Fantastic work for only 180 GBP. My Nakamichi MC 1000 with
beryllium cantilever got a new stylus by them. I bought this cart
despite the broken stylus and posted to Expert stylus as
an trial . Elsewhere I mentiond my carts and their ''ranking'' in the
context of Inna's new thread about MM carts.
