SP10 Mk II vs Mk III

Now, that's what I'm talking about!

The Steve Dobbins plinth looks great but the triangular plinth is just lovely. It would be nice to hear it as a motor tape-driving another platter since the MK3 has speed adjustment....

Hiho,

Lots of ways to do a plinth. I visited Mike about the time Steve delivered the plinth you linked to. Mike himself will tell you that these rebuilt tables will "play with the big boys" and his reference is the Rockport Sirius.

I like Steve's design and others as well. I agree the triangle design posted to that thread is unique, that's why we audiophiles get involved and do these things.

Yes, Albert, getting involved is one of the major fun of this hobby instead of always being lead by the nose by magazines and the so called experts. Glad to know the SP10 is in the "big boys league" instead of the doghouse.

By taking the motor out of the stock chassis really fires up the imagination, the sky is the limit. And this way the plinth plays an even more important role than before. Glad people are giving new life (and love) to these classic direct-drive turntables as the DD genre was getting very little press time for two decades.

I hope I will get to do that kind of plinth soon. Can't wait to see your new version in the future! :-)

By the way, for those on a smaller budget the SL1300/1400/1500mk2 series, which is essentially an SP15 with tonearm, is also perfect for this kind of treatment.

Hiho, Are you saying that for the SP10 MKII you just lengthen the wires from the chassis-bound electronics to the motor, when you install the motor only into a dedicated plinth? How long are the leads between the motor and its electronics when you get done with this mod? If it works, I am all for it. I just wonder whether it is dramatically better than just installing the whole assembly in a big piece of slate, as I and others have done. This says nothing about Mike Lavigne's MkIII set-up, of course. Despite what I wrote, I am tempted to try this with my second MkII, but I would also re-install the electronics into a cosmetically nice chassis. Six inches diameter for both the MkII and the MkIII?

The stock 12-strand wires come out of the motor assembly to the connector is about 8" long. I would extend the wires by at least three feet. I have three SP10's so I plan to do this soon. The important thing is that in the stock form, the motor is bolted to an 1/8" cast aluminum and the motor just hangs there. Now, imagine the motor mount directly to a thick slab of slate or wood or whatever material you like to use, don't you think that's better than the stock form? If you use the stock chassis, I don't care how wonderful your plinth will be your motor is still bolted to a thin sheet of aluminum hanging there. Just spend the time one day and carefully take the motor out of the stock chassis and then examine it yourself and you will know exactly what I am talking about. It's not rocket science. Almost ALL direct-drive can be improved this way. And for whatever reason, if you don't like the sound, just put it back to stock form - it's all reversible. The reason I haven't done it sooner is that I don't have the tools to cut slate! I would suggest keeping the stock chassis to house all the electronics because everything is all there with the buttons and switches, why re-invent the wheel? Unless it's an aesthetic issue and you just want to play around, go right ahead!

I plan to have two SP10 set up this way so I can have one tape-driving the other platter so it can be used as direct-drive and belt-drive. Fun!
