We use expressions ''retip'', ''refurbishing'' and ''rebuild'' without
any specification. What usually needs repair are new stylus with
or without new cantilever and damping. Nobody seems to repair
coils so if the coils are damaged a new generator would be the
only solution. What producers like Ortofon and Koetsu actually
do by ''rebuild'' is removing the old and putting a new generator
instead. One get a new cart in the ''old body'' this way.
