Warren Jones Posted December 28, 2020 Posted December 28, 2020 Interesting reviews. 40years on the SP10mk2 is still amongst the best TT ever made. I had the opportunity recently to hear the SP10R back to back with a modified mk2 and the 10R was not an order of magnitude better, the 10R was also on a MinusK. The mk2 was a motor mounted in a resin/bentonite plinth with electronics housed separate. A better platter on the mk2 and I suspect it will be equal to the 10R
Warren Jones Posted December 28, 2020 Posted December 28, 2020 This platter is destined for the modified mk2 in my last post. The impulse response is about as good as gets. First trace is the OEM second is the Stainless/Delrin platter. Testing was done in the plinth in the first pic with different setup to the previous plots so these will differ, it's the relative measurement between the 2 platters that we are interested in. Damping of the SS/Delrin is far superior. The ringing before and after is an artifact of tonearm resonance I did these measurements with tonearm damping off. This platter doesn't fit a stock SP10 so I couldn't do the measurements in the previous setup. 6
Warren Jones Posted January 3, 2021 Posted January 3, 2021 My spare SP10 motor died. Found the FG, which are the coils that provide the feedback to the PLL had a broken wire. The solution was to dismantle and rewind the coils. Took a few attempts to get it right as I broke the very thin 0.1mm wire a couple of times. Adjust it and now my spare SP10 is working again. Motor dismantled, this thing rings like a bell, I think some sound deadening is in order next time I pull it apart. FG coils ready to be assembled. FG assembled ready to be soldered back in place. 1 1

A decent tonearm and the SP10R would go ahead quite a bit I would think.
Warren Jones Posted January 3, 2021 Posted January 3, 2021 Both the SP10R and mk2 have SME IV arms. From my measurements the stock mk2 platter resonates, the SS/Delrin dampens this resonance far better than just the SS platter alone which is better than the OEM. Technics made a point of showing platter resonance test results in 10R blurb. The 10R platter is extremely well damped. Once I get the platter to the user I will get him to do impulse tests between the 10R and the SS/Delrin mk2, this will be interesting. Nelson Pass uses an SP10mk2 with a stainless Steel platter as their reference TT at shows over their mk3. Wayne Corburn from NP piped in on the DIY forum about their SS plattered mk2, this is what sent me down the road of making a SS platter. Next plan is to have a gunmetal blank cast and I'll machine this up and see how it performs against the SS 2

ianjackson1969 Posted January 22, 2021 Posted January 22, 2021 Hi everyone, Just thought I'd join in on this SP10 Mk2 appreciation thread. I've attached pictures of my rig as well as some of the cartridges I've collected. Cheers, Ian Jackson. 10
advanced concepts Posted January 22, 2021 Posted January 22, 2021 awsome setup love the cartridge arrangement . 1
Warren Jones Posted January 22, 2021 Posted January 22, 2021 Nice rig and great cartridge lineup the EPC P205mk4 I would love one of them. 1
ianjackson1969 Posted January 22, 2021 Posted January 22, 2021 Hi Warren, I scored this cartridge off ebay and then got lucky when there was a NOS stylus offered for auction on Buyee, the EPS-P205ED4. Sounds exquisite. I must say my introduction to MC carts was the 310. I'd never heard one before and then I partnered it up with my SUT and was amazed. I made the analogy to a friend, that a quality MM is like a razor sharp blade, whilst a MC is like that same blade sparkling in the sunlight. Cheers, Ian. 1
Warren Jones Posted January 22, 2021 Posted January 22, 2021 You need to upgrade the platter on the SP10, you will astounded at how this will improve the sound. 1
Warren Jones Posted January 25, 2021 Posted January 25, 2021 SP10 Gunmetal platter. This turned out a little undersize (317mm) so I didn't put the chamfer on the edge to keep mass as high as possible. I need to adjust the OD of the mold plug. It looks great on the black SP10. 7

I believe if I can hear a difference I can measure it, so that out of the way. Observe (eg listen) first, measure second - is the basis of good scientific methodology.

Owen Y Posted January 28, 2021 Posted January 28, 2021 Chaps - just a progress update on my SP-10 MkII journey... Now fitted with: - Terminator Linear tracking, Air-bearing tonearm - London Decca Super Gold with Decapod cartridge - Fidelity Research FR-64 arm - Koetsu Rosewood Signature cartridge I've had the latter 2 for many years, but never tried them together as a combo Cheers, Owen Dark Lantern blog - http://darklanternforowen.wordpress.com/ 2
Warren Jones Posted January 31, 2021 Posted January 31, 2021 Another platter upgrade, this time I bonded Derlin to the top of the gunmetal and machined it flat. This makes the gunmetal totally inert, hit it with a hammer and all you get is a dull thud. The 1kHz spectrum for the Delrin/GM is incredibly clean compared to the last plot which is the stock platter. The span is different but the sidebands on the OEM platter plot are obvious. Both plots were done using the same setup and the Ultimate Analog test LP. 2
mattb Posted February 6, 2021 Posted February 6, 2021 I'm also a big fan of the SP10. With some help from Owen (in thread above) I built a stacked plywood, MDF with lead/resin loading, layered plinth and installed two tonearms - the Transfi Terminator with AT33EV cart, and an SME3012 with a Ortofon SL15 ELL in SPU headshell. Setup sounds excellent and compares favourably to my Luxman PD444 rig. Thanks to Owen for his assistance in laying out the plinth and tips on setting up the Terminator! 3

Has anyone experience with this model? TECHNICS SP-10 MK2 PLINTH ONLY IN 2X20MM.ACRYLIC PLUS 3MM. COMPOSITE ALUMINIU https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com.au%2Fulk%2Fitm%2F264610424911 Hi, I have recently become an SP10 mk2 owner and have one of these plinths. I can't tell you how it compares to other plinth types, but can tell you it sounds amazing. It is susceptible to condensation (can see it in the photos - could be the Qld summer) but apart from that it sounds amazing (previously owned two Linn LP 12's). Very impressed and totally understand how these turntables have their reputation - a source component of the highest quality. A keeper
Warren Jones Posted February 28, 2021 Posted February 28, 2021 Welcome to the club, I was also an LP12 owner for many years, and you're correct the SP10 has huge potential.

Hi Warren, thanks for your response - your SP10's look awesome - the parallel tracking arm is of interest to me as I also own an SL10 and whilst it is not in the same league as an SP10 - it does many things incredibly well and I can't help feeling that the parallel tracking arm is contributing significantly to this. Your work seems to be bearing this out ; also the new platter material /construction you are trying. Very interesting and so glad that someone is exploring the the boundaries. cheers Cameron

Warren Jones Posted February 28, 2021 Posted February 28, 2021 Here is my latest creation, my SP10mk2 Platinum with an extensive list of modifications. I have gone to great lengths to reduce and isolate vibration as much as possible. How does it sound - lets put it this way I am hearing detail in familiar music I have never heard before. And yes my EPA100 is modified too with a new CW stub SS CW and locking ring, with variable viscous damping. Resin Bentonite plinth.

I was quite skeptical when I got it but it grips the platter and record, and provides more platter dampening than that the original mat, which is twice as thick. Pete
