Default The Incredible Technics SP-10 MK3 Thread

In the same vein as 6L6's MK2 thread, I thought we should start one for a related, formidable, Technics beast.

There's not a lot of information out there on these, even if you can read Japanese, or want to try your luck at deciphering Google Translate... Sometimes I think reading Japanese would be easier.

Should any pertinent links or information come up, I'll try to document them in this first post. Skip down to get to the good stuff.

This is my next project, (relatively) fresh from Japan. Aside from some small scratches and dings in the chassis, a dent in the top of the control box, and a platter in desperate need of some polish, it's in better shape than I thought.

After unboxing and throwing on the platter, I put it on my step-down converter and gave it a spin. I'm pleased to report that everything is working as it should. I did notice some green legged caps in controller, so ~30 seconds is all I'll do until I finish the refurb. I didn't really want to run it at all, but I had to make sure it was as advertised and the listing pictures showed it powered on, so I took the chance.

While I'm waiting for my parts order, I decided to take a look at the bearing.

To remove the back cover, remove all the screws. Unlike the MKII/2A, they're all the same, and are self-tapping. The back cover is a composite material similar to the sub-plinth on the 1200MK2. There is a rubber gasket, so you need to get a good grip and give it a shake or two for it to break loose.

Some of the soldering leaves a lot to be desired.

Dual brake solenoids. One is for a band brake like the MKII/2A, and the other is a lever brake.

The bearing thrust cap on this 'table is open, so one consequence of over lubrication is that the oil leaks out.

Click the image to open in full size.

A 2.5mm hex key for the three socket head cap screws will liberate the bearing cap. From there the "C" retainer slides right off, freeing the shaft which you can pull out from the top-side.

On this one the wear on the shaft and bore appear to be very minimal, and I noticed the fit is very tight. Just with light oil there's enough resistance that you'd think it was lubricated with light grease.

Now, the one thing that perplexes me is that I'm used to seeing light machine oil, which I presume is similar to the Technics oil, become gummy and amber in color when it's old. The only sign of oil not being oil anymore here is at the thrust bearing. However, this stuff has a consistency more like light grease than old gummy oil. This could be the way the Technics oil breaks down, or this could be some kind of grease only on the thrust bearing. Any ideas?

Mystery solved, unfortunately. The thrust bearing is ceramic, and the brown gunk is ground up bearing and oil. The ceramic on mine has taken and impact and has been damaged. Time to figure out how to replace it, and with what. I'm more than open to suggestions on this one...

15 minutes in the toaster oven at 375F broke down the glue. Popped it out, cleaned everything up, and glued it back in with the fresh side facing up. Good to go.
