My word, you're getting yourself a collection of them!

One SP-10 is for a friend, one is for parts, the SP-15 will be for sale...
I think I wil have enough with one (with 2 arms).
BTW, the main arms are the fabulous PU-7 from AudioOrigami,

Mine are custom made, all brass, 11" long.

Are the SP-10s generally repairable/maintainable? I've been thinking of buying one, but they are getting on in years, and have a lot of electronics in them, yes? Any hard to obtain parts?

Parts can be hard to find. But you usually do not need any.
They are built to last.

SP-10's are more complicated to repair, but the parts are more common. They are based on older technology where as the SP-15 is based on newer tech but have 3 proprietery chips in them that simple do not exist anymore and there are no known cross references for them.

I specialize in SP-15 repair but have pretty much gotten out of keeping up with them. see my website at www.overkillaudioinc.com for some of the products i once offered.

The SP-15 is a great 78rpm table but not a very good high end audiophile type table. the motor is way too big and has lots of cogging to be a good 33rpm table. Remember the Sp-15 was never designed to be a home table. it was designed as a radio station table.

The Sp-10's have MANY more poles to the motor's reducing cogging at low speeds. Plus they have a much better thrust bearing arraingment. the SP-15 Thrust bearing is very very weak.

At one point i was manufacturing replacement thrust bearings design in conjunction witn Simon York. But My machinist has since retired and i have decided not to contiune making them as the cost of MFG is just to high for what i can sell them for.

Another weak point for the SP-15 is that the spindle is very weak and easily bent. that 7lb platter is riding on it and one sharp blow to the edge of the platter and that spindle is bent! 99% of the table i get in here have bent spindles. I have to pay a machine shop to straighten them.

My personal fav is the SP-10 MKIII with the external PSU that has 3 speeds (hard to fine) mated with a SME 3012R arm and a variety of cartridges.

But does not the MkIII have the same motor as SP-15?
I have not held one in my hand(MkIII), but seen several pictures...?
I was also told from another source that the SP-15 was an upgraded 1210 motor?
And a third source say the SP-15 had (marginally) better data than SP-10 ?

Anyway...I'm happy as a .....
