Big, BIG tangential turntable of the sonically successful kind.
Produced in rather sizeable amounts, contrarily to what might one believe and the original 180,000¥ list price : like the smaller PX-3, there are plenty of PX-2s around.
The original PX-1 mammoth gave way to more acceptable designs, but still filled with sensors of all kinds to properly keep the tangential tonearm... tangential to the record groove - electronica here we come !
The path opened first by Sony and the PS-B80 in 1977/78 was quickly followed by many, for our auditive pleasure.
I only know of two other tangential turntables sonically as fully satisfying as the PX-2 : the Technics SL-10 and the Sony PS-X800.
The latter had somewhat gimmicky looks which probably kept it from becoming a serious "audiophile" seller while the former had stark, dark, too dark, "serious audiophile" looks written all over itself.
Make the PX-2 a dark grey à la TA-N86B and I'm in.
Beyond the aluminium diecast frame, the base of the PX-2 and PX-3 is made of BMC btw : Bulk Mold Compound, as in SBMC or... Sony BMC :)
Excellent vinyl players at any rate, worth their reputation.
Check this page for a PX-2 in the studio.
2011 : original japanese catalogs finally at hand - stay tuned.
