We all think in the same way but have different assertions which
we use as premises. The first logical rule is that wrong or
false premise can never lead to true conclusions.
The most believe that the stylus is the most important part
so the fear about ''hours of use'' determine our preference
for new or second hand. But one should look at this unclear
notion of ''refurbishing'' from the retipper situation. What parts
he has in his stock, what parts are available and not available
to him. The ''rubber ring'' or suspension, for example , is
more important than stylus shape. The same apply for the
cantilever not to mention coils. No retipper will mess with
coils. If the coils of your cart are defective forget repair
possibility. Think of those ''rubber rings''. How many kinds
are available to a particular retipper? Can carts be ''tuned''
without suspension?
Ergo: the least ''harmful'' repair is the stylus exchange.
@bimasta, you mentioned that your Koetsu has ''perfect''
cantilever. Post your cart to ''Expert stylus'' in UK their
''Paratrace'' stylus is an version of micro ridge. Their
retipper Mr. Hodgson is engineer with 40 years of experience.
