Sony PS-X9

JP does have one that came with an SME arm mounting board,
if I recall correctly replacing it with another original board
was proving very difficult.

If you're referring to replacement of the tonearm mount, that's neither here nor there, as regards the "goodness" of a PS-X9.

Looking at the way arms have an integrated mounting as shown 
in the Ebay listing any substations look problematic.

@best-groove
with the $ 10,000 surplus, do you know how many renovations of PS-X9 can be achieved? Many!

I recall perhaps 4 years back a fellow Canadian was transporting 
a Sony PS-X9 across the US Canadian border and was nabbed 
for not declaring the correct value, he paid the levied fine
but then had an issue he was not able to rectify.

Never heard back after that.
