Dear chakster, the logic of identity relation is not easy to grasp
but the rule is that the same name refer to the same object. There
are however different names which refer to the same object but
we somehow have no problem with those. Say Vienna , Wenen,
Bec, etc. refer to the same city in Austria which Austrians name
Wien. The logical rule is then that whatever is true about Vienna
is also true about Wien, Wenen (Dutch name) and Bec (Serbian
name). So your statement ''ZYX is not ZYX'' is at least confusing.
I think that your meant ''the old ZYX is no more the new ZYX''.
The old Nandric is, alas, also no more the young one.
I ever started a thread about ''irreparable'' cartridge but nobody was
interested. My reason was my Sony XL 88 D as well the ZYX.
Their body is made from ''plastic'' which is glued together so
there is no entrance to the inside parts. The Sony was probably the
first cart which was ''potted'' so nobody was willing to mess with
this cart. Axel try for two years and give up. But he fixed my ZYX
by cutting some parts from the body in order to get access to
the generator and suspension. If your new ZYX is even more
difficult to fix or rather impossible to fix then I am sorry for you
considering the old as well the new prices for both ZYX kinds.
Even if any of those ZYX is made and delivered from Eldorado
I would not even dream to buy one (grin).
