List of plinth builders for Technics SP10 MK3

I am sure that Dr Kaneta is one of the great geniuses of all time, in the category of an Einstein. That wasn’t my point. Apologies to his family if I did not pay heed to his seminal contributions to audio.  I would still credit Steve Dobbins with explanting the SP10 Mk3 motor assembly, although the idea to do it was already “in the wind”.  Peter Reinders is a great guy who was uncommonly generous some years ago in openly sharing his design for both the PTP Top Plate and the use of a slate plinth and how to cut it for a Lenco.  Slate was later replaced by Corian in the commercial version of his plinth.  Thanks to Peter, I was able to commission the construction of a slate plinth for my Lenco, using the first commercial version of his top plate.

Strictly speaking, I think the Kaneta plinth was designed for the mk2 and not the mk3. The two chassis’ present distinctly different issues, because the mk2 is larger below the surface and houses all the electronics. Thus re-plinthing, if you want to separate the motor from the electronics, requires also that you build a box for the latter. The mk3 is actually easier to upgrade in that regard; the motor is fairly easy to remove from the small round housing found below the visible upper surface of a mk3. For my mk3, I commissioned a large heavy slate that houses the OEM assembly. Below that I installed a bearing damper a la Porter. And below that a substantial solid cherrywood base that bolts to the slate. IOW, I elected not to follow Dobbins’ idea, although I greatly admire his work. I succeeded in making my mk3 so heavy that I cannot lift it without assistance. I’ve also done the Krebs mod, and I’ve upgraded the chip a la JP Jones. I’m done.

 

Rich, if you want to use slate and if you opt not to do the Dobbins mod, I can offer some guidance. I think I still have the pdf file that was used to program the water jet to cut the slate.

Rich, surely you’re aware of Albert Porter’s panzerholz plinth for the mk3. Has he ceased to sell them?

Thx, but like I said, Rich has a mk3, and my remarks about shedding the outer chassis were only as regards the mk3. And it’s been done many times before by various companies. The motor of the mk3 is apparently easy to dissect from its chassis.

I was only thinking of the mk3, where electronics are outboard. It’s been done by many, including Steve Dobbins. Probably OMA too.

For two tone arms, I think you might consider building a plinth that encloses the motor only. In other words, get rid of the rectangular escutcheon that sits on top of the surface of most plinths for the mk2 and mk3. Once you get rid of the escutcheon, there is much more room for two tone arms and 9 inch tonearms. Even a single 9 incher won’t work well with that escutcheon in the way.
