First, I don't know exactly what three ICs you're referring to. So far as I know, at least for the SP10 Mk2 and Mk3, there is one irreplaceable IC which I am too lazy to look up but which goes by part #MNXXX (where the Xs represent a numerical designation). The functions of this IC can now be replaced by a tiny PCB containing discrete SMDs, the same size as the NOS IC, that has been developed by JP Jones in NYC. Furthermore, JP's creation works a bit better than the original IC to control platter speed, based on measurements (not listening tests only). The cost of the IC and its installation by JP is only a few hundred dollars, which makes lots of sense if you own a Mk2 or Mk3. I don't know what's up with the SP25, but I would have thought it shares parts in common with the Mk2, at least. In fairness, the SP25 is a nice turntable but by no means does it represent Technics' best effort. If it's fundamentally like the Mk2 and Mk3 in regards to speed control, JPs PCB ought to be able to restore operation to SP25s (and SP15s) that have had a similar failure.
