Apparently the MK7 is not a good candidate. I like the idea of coreless stators, which should in theory make the motor quieter, but unfortunately because Technics have opted to "eliminated the root cause of cogging" by removing the cores, they no longer need all the great cirtuitry that made the 1210 so stable for cutting. I will unpack that in a later post.cutz wrote: ↑Fri Sep 08, 2023 5:52 pmI came across this old thread and wanted to updated it.
Apparently the torque on the newer Technics SL-1200MK7 can be adjusted rather easily. They also are able to play in reverse not sure how that would apply to this community but worth mentioning. These new decks have the digital pitch control rather than the analog pitch control included in the first iterations of the 1200 models (apparently the analog pitch control is more desirable for more precise beat matching). Also worth noting that Panasonic quietly fixed the pitch control on these newer MK7s because the first batch of turntables were 'inactive' around +-7-8.

I don't have one myself as I'm still rocking a MK2 and MK3D. I prefer the MK3D because there is no middle notch in pitch control so you can really fine tune when you are around +-0.
Before I cam up on a ROK, I was considering getting the MK7 to use with a VR lathe because of this new torque adjustment everyone was going on about. Might be something to research and consider still.
Of course as other vets on here have mentioned, go to piaptk's lathe camp, see if this is something you really want to get into, get a lathe, practice and see where to go next.
Unfortunately, the torque of a motor (published or even measured) cannot be used as a proxy for cutting suitability. I learnt that the hard way by buying a Numark turntable (possibly a tt-500) and found it to be almost completely useless for cutting. Maybe if a very heavy platter was added it could have served as something akin to a decent belt-drive, but I wasn't in a position to test that theory, and that was not really what I was going for.farmersplow wrote: ↑Sat Dec 30, 2023 4:22 pmAdditional note: As far as I know, the Numark TT-500 has the same motor as the TTX, but can be found used more often and cheaper. Torque: 4.5 kgf.cm (temporary); 3.5 kgf.cm (stable)
I wouldn't recommend any turntable based on spec alone, and that includes those used in some very high end lathes. The only way to know if a given system suits your requirements (more on this later) is to test it. The condition of an SP-15 is a factor, as speed problems have been reported with aging units.A1-Voodoo wrote: ↑Mon Jan 29, 2024 6:12 am@Dub Studio - Besides the MK2 with the resistor mod to get up to 2kg, what do you think about the Technics SP-15 with 3kg starting torque for use with a VR and the precision platter? I'm researching all the available options on there and was thinking that would be a decent torque vs money unit...? Sure everyone wants an SP-10MK3 and all... but that price!
To the OP, the SP-15 does not hit the price point your looking for (more expensive) - apologies for thread jacking momentarily.
Thanks, I am surprised there is such a big difference - 70g versus 500g! This would certainly encourage me to try an SP-15, but again I think the proof is always in the pudding.Tom The Phonocat wrote: ↑Mon Jan 29, 2024 1:11 pm@Dub Studio - I am currently cutting with SP15. It has been freshly serviced. It can withstand around 70 g of weight. I also have a sp10mk2 and this can withstand easily around 500g.. Did a very non-scientific test. I bought myself a digital scale spoon (for spices and such). Placed a phone with a RPM measuring app on the platter and started to apply pressure with a spoon. These were the values which started to slow down the motor .. the Rotation was buttery smooth until I hit those... Of course..it may seem a childish way of checking it... but in reality, I cut on sp15 now and no audible wow even on 25 g. .. I have cut a groove as wide as 90um and no wow. Sp15 is a beast .
It's not 100% solid. It moves a tiny bit back and forth (by a tiny margin ), but the rotation of the platter is stable as hell according to the RPM app (wow and flutter values are also low)... This could be my SP too. I have a recapped BBC version with their microswitches.. it was a pain in the ass to revert it . I couldn't use the original Start/stop when i got it:P
Yeah, I wonder how accurate those markings are... I mean if the machining itself is off slightly, it's going to look like its not stable. I also wonder about the wow and flutter app... how accurate is that, and how can we know for sure?Tom The Phonocat wrote: ↑Fri Feb 02, 2024 7:36 amIt's not 100% solid.

I don't know to be honest but I usually cut with 15-17 grams on head with dashpot. These are the releases I did with SP15 + some more for other people, mostly this type of music:
