New Turntable Advice

Good advice yes my Sony PS-X700 has the same encoder on inside of the platter!!

Stethoscope great idea for the bearing. Is there a new model which is at the same precision as the Sp10 Mark II? 
 

thanks great Advice 

The fella that refurbished my Sony PS-x700 is here in the states. He specializes in Japanese TT.  He has both a Nak, and a X9. I'll go see them but will also weight these other tables 

In my time of working with JVDD TT's, I have taken Barium Ferrite and other Coatings that are an equivalent, becoming damaged as a serious consideration. As said, I have bought into having spare Platters to be available where possible.

Note: Platters show occasionally not monthly, maybe yearly if searches are maintained, but not for Sony Models I own. 

 The SP10 MkII Platter purchases are nothing to do with Peripheral Magnet Coatings, most bought are probably due to me being a hoarder, and having friends with their own designs for the MkII Platter hence the gifting of platters. 

If I knew what I did today, I would own Yamaha and Micro Seiki over Sony and Denon as a multiple unit purchase, even though finding the cheaper sale models will have been over a longer period of purchasing. Reason being each are not using a Platter with a Periphery Magnet and each have models with the Electronics that are Off Board from the TT itself. These base designs will prove to be very easy to create the Kaneta Design, incorporating a Resin Impregnated Densified Wood Chassis/Plinth.

Hind Sight is always a good manager, but after having heard the Kaneta Version of the SP10 MkII and getting the core instinct the design is eking more than is already offered from a modified MkII. Stimulates the idea that a TT that is able to be produced as a Kaneta Design using Resin Impregnated Densified Wood Chassis/Plinth, is to be easily discovered as an improvement over the original design for the TT. Add to this other Treatments for the Mechanical Interfaces to add modern materials and remove the metal on metal contact that does occur and the possibilities become a whole new area of interest.   

The SR 510 is also suitable for redesign for the Platter and is to be investigated to be used as a Kaneta Design, a Bearing Housing / Stator Bowl and with Electrical Lead Outs is purchased and to be learnt if the already produced electronics are able to create Spindle Rotation, Speed Control will be the challenge for this design change..

With what I know about Platter availability for certain Sony Models, and the cost I have seen models command, the idea that one minor damage puts the TT out of service is not a good condition to have running parallel with a very expensive purchase.

Does a Vendor actually inform that the Magnetic Coating in intact and no evidence of a damage to the coating is able to be seen??? 

If we were talking near $500ish, I would not say too much, one pays their monies and takes their chance. The TT is not too different from a sacrificial Cart', being after 'X' amount of hours in service it is spent.

The OP is into going up to $5K without an arm, I am not directing the OP towards any TT, that can have a really short lifespan due to being obsolete as a model and not known to have support readily available to correct a Barium Ferrite Damage.

If different is known to my experience of investigating Periphery Magnet Damage Repairs, I am all ears to learn what is known   

As for the statement " not known to have support to correct a Barium Ferrite Damage.

I have too many years of looking for the fix, which has never been found.

I once found a TT which had a Platter Fixed that had a magnetic sensor design, where disc magnets were used as an alternative, the TT is not remembered as my PC crashed and the Bookmark went down the swanny. 

A repair has never been discovered by myself that was a duplicate of the one lost  or any other methodology as the repair.

There is the odd report seen where a TT owner is to claim they are able to use a TT with a Periphery Magnet Coating Damage, but these are very uncommon as report.    

After doing many searches in many Countries, what is known and seen in a fair amount of forums, is that Magnetic Coated Periphery Rims on TT Platters get damaged from simple user mistakes, no different on simplicity to the simple user mistake made that trashes a Cart'.

Magnetic Coated Peripherals are Very Very Fragile - Non Repairable? - Spare Parts are Very Very Rare!! - Found on Very Very Expensive TT Models!! - Act in Haste - Repent at Leisure - Learn to Enjoy what might become a TT Ornament .       

The current top of the line Technics is the SP10R. With plinth, it’s the SP1000R. But that model is more on par with the SP10 mk3, both superior to the SP10 mk2, and far more expensive. (I’ve owned both mk2 and mk3, and I conferred a few years ago with JP Jones who owns both a mk3 and a new SP10R and has measured the performance of both.) 

Very Very Subjective about the MkII and MkIII, the individual based in the UK who is renowned for their work on the Technics TT's and who has designed the improved speed control for the MkII, is not convinced the MkIII is offering much as a betterment.

I stand by their evaluation, one can spend $5K to $7K on a MkIII in todays money and for $1K +/- $300 have a MkII that will be quite a attractive TT. 

Add to the MkII the bespoke design speed control and the MkIII is not too different, if any different.   

As for the Mk III, I have never encountered one in use in a System I am familiar with. The SP 10R is different, where during certain periods of a year, the SP10 R is experienced in use with a Valve Phon' sharing close design to my own, along with Valve Amp's and ESL's on more occasions in this system than my own MkII used with Valve Amp's and ESL's in the home system. 

I know the SP10 R very very well as a TT, and can only say good thing about it. 

I suggest if a properly attended to MkII with bespoke designed speed control and mounted in a Densified Wood Plinth and a SP10 R were side by side in comparison. Using a same TA and Cart', It would be a lot of swapping out of the TT's, to discover where there is a valuable difference to be discovered. I don't see that occurring with any easy outcome as a subjective evaluation.

I do know the Kaneta design that is loaned and is regularly used in another system where it used with a Tonearm Identical to my own, but has replaced a MkII finished to the same Spec' as my own, inclusive of a P'holz Plinth. The Kaneta used in the system, now has the system owner making it known the Kaneta design has won their preference, when they use their MkII, there seems something is amiss. 

I need to make my TT and Tonearm available, so that both the Kaneta and MkII, can be heard with identical TA's and the Two Kontrapunkt B's that are owned within the audio group and kept with low hours usage for such occasions. This is the session yet to be done, that will help discern the differences from the variation of the designs for the TT's. 

The Kaneta lends itself to both Platter redesign and Bearing redesign, the whole shebang will still be considerably less of a cost to create than the cost of a Mk III which may have had a very very hard and uncared for usage life prior to being purchased.

Note: A used sale item that is a Vintage Era TT, typically comes with no service history or knowledge of how may rotations have been carried out. How used a TT is remains a mystery? How abused a TT has had to endure remains a mystery?  

Using the assessment of a Technics TT Specialist renowned in the UK for the work undertaken and for knowing the additional adaptations that are able to be done to the Mk II, the Mk III is not a TT that creates any real interest.

The Mk III, in the current market is for my usual budgeting, too expensive to purchase and then donate it to be toyed with and too expensive to acquire duplicates to compare design changes. 

VFM is to be found with the Mk II, as I would id searching prudently, be able to acquire approx' 7 - 10 Models imported and duties paid for the cost of 1 x Mk III
